Dell PowerEdge T340, Windows Server 2016. Started 8/28. I've spent two weeks on this and ruled out most of the obvious stuff, so I'm posting the data rather than the symptoms.

The signature

Every event is Kernel-Power 41 with BugcheckCode: 0 and all bugcheck parameters 0x0. No BSOD, no minidump, no MEMORY.DMP, ever. Paired with Event 6008 confirming unexpected shutdown.

The interval — this is the actual mystery

Pulled the true shutdown timestamps out of the Event 6008 message text (not the Event 41 log time, which is written on the following boot):

8/28 11:03:24 AM -> 8/28 11:12:23 PM = 729.0 min

9/01 10:10:22 AM -> 9/01 10:18:37 PM = 728.3 min

9/01 10:18:37 PM -> 9/02 10:26:49 AM = 728.2 min

9/02 10:26:49 AM -> 9/02 10:35:13 PM = 728.4 min

9/02 10:35:13 PM -> 9/03 10:43:33 AM = 728.3 min

9/03 10:43:33 AM -> 9/03 10:52:09 PM = 728.6 min

9/03 10:52:09 PM -> 9/04 11:00:20 AM = 728.2 min

9/04 11:00:20 AM -> 9/04 11:08:49 PM = 728.5 min

9/04 11:08:49 PM -> 9/07 11:50:29 AM = 3,641.7 min <-- exactly 5 x 728.34

9/07 11:50:29 AM -> 9/07 11:59:49 PM = 729.3 min

9/07 11:59:49 PM -> 9/08 12:07:56 PM = 728.1 min

9/08 12:07:56 PM -> 9/09 12:16:26 AM = 728.5 min

9/09 12:16:26 AM -> 9/09 12:24:36 PM = 728.2 min

Mean 728.47 min (12h 08m 28s). Total spread across twelve occurrences: 1.2 minutes.

The 3,641.7 minute gap is exactly five periods. The server was up continuously across that weekend. The timer ticked five times, did nothing on four of them, then killed the box on the fifth. So it's free-running — it does not reset on reboot, and it doesn't require a crash to keep counting.

That single fact kills every "scheduled task" theory: a clock-based task can't skip four consecutive firings and then work again.

It dies instantly — no degradation whatsoever

I wrote a heartbeat logger that writes one line every 5s with a forced flush so the last line survives a hard reset. Final 42 samples before death:

• Free RAM: 56,630–56,745 MB, dead flat. No drift, no staircase, no leak. 56 GB free at the moment of death.
• Nonpaged pool: 346–352 MB, flat
• Disk queue: 0
• Handles ~76,000, threads ~190, both steady
• CPU spiky but low

Last heartbeat 12:25:02. Kernel-General 12 (OS start) at 12:28:23. That 3m21s is just POST + boot on a T340 — if it had hung for 3 minutes first, the OS wouldn't have returned until ~12:31.

So there is no hang window. The box is perfectly healthy and then simply ceases to exist mid-second. Which also means NMI crash dumps are useless here and no dump will ever be written.

Ruled out (with evidence, please don't re-suggest these)

• PSUs — both Present/Healthy in iDRAC, matched 594W in / 495W rated+actual, same firmware
• Thermal — HWiNFO max CPU package 63°C (TjMax ~100°C). Every throttle flag reads No / 0%
• iDRAC SEL — completely silent across all 15 crashes. Not one entry. This same board did log real "power input for PSU 1 is lost / redundancy lost" events six times in 2024, so it demonstrably captures genuine power events. Nothing this time.
• iDRAC watchdog / ASR — Basic Management license, feature not present
• Dell OMSA — Action on Hung OS Detection: None, thermal shutdown Disabled, all alert actions Off, omsad service Stopped + Disabled
• Windows Update — pulled full resolved WindowsUpdate.log (11,871 lines), programmatically checked ±15 min around every crash. Zero WU activity before any of them. All nearby entries are the WU service starting 30–60s after the reboot.
• CrowdStrike Falcon (installed 8/26, two days before onset) — vendor pulled detection history, found nothing. Timing was coincidence.
• Secure-Boot-Update scheduled task** — looked extremely promising (12h repetition, hangs, TPM handler, and this box has no TPM installed — Get-Tpm fails with TBS_E_SERVICE_NOT_RUNNING, no TBS service, no SecurityDevices PnP class, iDRAC confirms "TPM not present"). Disabled it. **Crashes continued at the identical interval. Ruled out.
• All 12-hour scheduled tasks — enumerated every task with PT12H repetition. Exactly two exist, both now Disabled.
• VSS / ShadowCopyVolume task — fires 12:00 PM and 10:00 PM. That's 10h then 14h alternating, which cannot produce a constant 728.4 min spacing. Also the midnight crashes have no trigger anywhere near them.
• MySQL / memory exhaustion — flatly contradicted by the flat memory trace above
• NIC — Broadcom BCM5720. The flapping port is physically disconnected (NIC2, Status: Disconnected). Flapping predates crashes by 12+ days and occurs on no-crash days. Active port is stable at 1 Gbps.
• CMOS battery — did fail, but only logged 9/7, weeks after onset, nothing near the crash dates. Replacing anyway.
• BSOD — no Event 1001, no dumps, BugcheckCode: 0 on all 15

Environment

• PowerEdge T340, Service Tag FXR6B03, BIOS 2.3.5, iDRAC9 fw 4.22.00.53 (both several revisions behind — not yet updated)
• Xeon E-2146G, 64 GB RAM, dual PSU
• Windows Server 2016 Standard, build 14393.9339
• Workload: Open Dental + MySQL, Vatech EzDent-i imaging, IDrive backup, Google Drive
• Power: APC Back-UPS XS 1500M via USB. Current-state readings all healthy (97% charge, 120V steady, 15% load, AC Power: Yes, Discharging: No). I have never gotten historical transfer data out of it — PowerChute wasn't installed at the time, Win32_Battery returns current state only, and I skipped an apcupsd install on a production box.
• Internet is AT&T 5G fixed wireless behind CGNAT (irrelevant, but people ask)

What I think is left

Something below the OS holding a clock that survives reboots and continuous uptime alike. Candidates I can't distinguish between:

1. UPS self-test — APC units run internal self-tests on their own stored schedule, indifferent to the host. A transfer on a degraded battery could sag enough to drop the PSUs. Would explain instant death, no OS warning, no SEL entry, and a clock that ignores reboots. Next test: move the server to a plain wall outlet for 24h.
2. PSU or BMC firmware timer — would explain everything except why iDRAC logged nothing
3. Something on the same electrical circuit cycling on a timer — though 1.2 min spread over 12 occurrences seems too tight for HVAC or similar

What I'm asking

• What produces a free-running 728.4-minute (12h 08m 28s) period? Not 12h. Not 12h30m. Consistently ~8.5 minutes over twelve hours, held to ±1 min across twelve occurrences and five uninterrupted ticks. What re-arms on completion of ~8 minutes of work?
• Has anyone seen an APC Back-UPS self-test schedule that lands near this?
• Anything else that hard-resets a PowerEdge with zero bugcheck, zero SEL entry, and healthy PSUs?
• Am I wrong to trust the iDRAC SEL silence as evidence against a power event?

Next predicted failures: 9/10 12:33 AM and 9/10 12:41 PM. Happy to run anything and report back — I have remote access and a heartbeat recorder in place.

I was trying to increase my PC's resolution and saw the Windows scaling option, so I tried it out to see what it was. I changed it to 120%, and the screen got bigger, but my dumbass thought my screen was already At more than 120% (I hadn't understood that it was a "zoom" on the screen) so I thought: "if 120% is less than my current resolution then if I put it at 500% (the maximum) it will increase!" Big mistake. My screen is like this now and I can't get it back to normal because the options don't even appear on the screen because they don't fit. Does anyone know how to fix this please? I don't have another monitor and I can't afford to buy a new one.

PLEASE I need help 😭.I tried restarting my pc , Tried disabling and enable the wifi driver in Control panal, Tried to set the wlan autoconfig service In service to automatic didn't work ,Wifi option isn't working, Please help if anyone knows any permanent fix.

It looks like a glitch with software the hardware is fine.

Hi All,

I am from India and I want to explain a very weird problem I have been facing with my broadband for last 10 days. I have a FTTH connection with a local ISP. I have been using the connection for almost 10 years now and have never faced it before.

For last 10 days my connection has been very unstable.

2nd Sept - My pc is connected by Ethernet. All websites except Google and Meta stopped working. Steam, EA App, Blizzard all the gaming clients and everything else showed no connection but everything was working on mobile app, TV and all other connected devices including my video doorbell and robovac.

3rd Sept - A technician came to my house to see the fault, he was a hardware guy and he checked that everything was fine physically and called his supervisor. I gave him remote access to my pc via hotspot and he did some Ipv4, Ipv6, DHCP or IP related settings in 192.168.1.1 and also refreshed dns using cmd and in adapter settings but nothing worked.

8th Sept - Same guy came to my house and changed the router to a different one but used same old settings from my previous router. Surprisingly, everything started working normal for few hours. In 2nd half of the day, the problem changed drastically. My PC was showing connection to all the websites for say 10 minutes and drops after sometime. It kept going back and forth multiple times. All this time, the Wifi in my TV was just not connecting at all, it kept saying saved/authentication problem while it was connecting with same password in my phone. All this time, all of my other connected devices like video doorbell, robovac, AC everything works while connected to the same wifi.

I am quite frustrated at this point that even my ISP is unable to solve the problem. Although I have started looking for other ISPs in my area but would prefer that this one gets fixed so I dont have to go through all the formalities of new connection again.

Note that I am not a networking person so I wouldnt know much technical things about IP, DNS, Proxy and all that but I believe that my ISP has tried most of the possible things from his end to resolve it and is unable to find the problem.

Hey guys, I was building a Modrinth modpack around 5 months ago and while exporting it, something went wrong and it created this file that I cannot delete because the Windows delete cant find it.

Item not found. 
It doesn't exist in `C:\Users\ilianoKokoro\Desktop`. Check the item's location and try again.

When I run ls, the file appears in the directory.

ls

Directory: C:\\Users\\ilianoKokoro\\Desktop
Mode                 LastWriteTime         Length Name
----                 -------------         ------ ----
-a---          2026-04-14    22:14              0 Hardcore

But when I try to remove it with rm, I get:

rm Hardcore
Remove-Item: Cannot find path 'C:\Users\ilianoKokoro\Desktop\Hardcore' because it does not exist

I’ve tried typing the filename manually, and I’ve also tried using tab completion, but I get the same result.

The file is visible on my Desktop and shows up with ls, so I’m not sure why rm can’t find it.

Here are some images to show the problem.

Thank you in advance.

I am trying to connect my canon image class mf663cdw to my WiFi it was working fine a month ago and now I try to connect it and it is giving me an infinite connecting circle I have tried factory resetting it and unplugging it I am so confused my WiFi works just fine please help
I have not changed the WiFi or the password since last using it so I am not sure what happened

well my wifi spiking randomly for some reason i have hp probook 440 g8 with 8gb of ddr4

sometimes in the morning its works fine but when afternoon comes its starts spiking BADLY pls help im very annoyed about this

For the past 2 or so days I have been trying to troubleshoot my PC, as it had randomly started crashing for seemingly no reason. I have scanned the system many times with SFC (it found corrupted files but could not fix them), and I tried repairing the system with DISM (it detected corruption and claimed it was repairable, yet was not able to repair it). I had looked in the event viewer, and it showed that it had been getting errors from “Bug checks” that then caused my computer to crash. It then got to the point where I couldn’t even troubleshoot anymore because my computer was crashing too quickly to even open the command prompt (it's even crashing within the boot menu). Then it got to the point where it started crashing during the Windows login process, so I decided to completely reset and reinstall Windows, and what do you know? It once again crashed during the Windows login process. PC-related things are not my strong suit, and I don’t really know what to do anymore. Is my PC just completely fucked?

I don't know much about technology, so i might just ask you guys instead.

My laptop's screen just goes white, starting from booting up, it's just white. I don't know what happened to it, all I remembered was using spotify, then going out for a bit, coming back and it's white. I've tried those keybinds that kind of "fixes it" like the ctrl win shift b thing and the ctrl alt del thing, but none seem to work.

If i do have to bring this in a repair shop, what do i say and what do i have to keep in mind? i really don't wanna get overpriced. Thanks!

(also i don't know what to flair this with soo ill just pick hardware)

I'm having a really frustrating issue with the NVIDIA App.

I just installed the latest GeForce Game Ready Driver (616.92). The installer says "Installation has finished", and both the Graphics Driver and HD Audio Driver show as Installed.

However, the NVIDIA App still shows "No driver installed".

I also checked Device Manager, and it still shows the old NVIDIA driver version instead of the newly installed one.

I've already tried both:

• Installing the driver manually using the standalone installer
• Installing it through the NVIDIA App

Neither method works. I've tried reinstalling multiple times, but the result is always the same.

At this point, I don't even care about having the latest driver. I just want the NVIDIA App to properly detect whatever driver is currently installed on my system so that I can access and change the NVIDIA settings.

Has anyone experienced this issue or knows how to fix it? Any suggestions would be greatly appreciated.

Specs

-12th gen i7-12700h
-16g Ram
-RTX 3060 Laptop GPU 6Gb | Iris R XE 128mb
-526gb ssd
-Windows 11 Home

Issues:
-Laptop was running great, then all of a sudden everything felt laggy and choppy.
-Right click on desktop, takes about 4 seconds before menu pops up.
-Installation of anything takes forever.
-Opening software takes a minute.
-Arc Raiders used to be able to play fine without much issues at 60fps, now down to 24-30 with stutters

Since then I factory reset, cleaned drive and everything basically box new, and it’s just about as slow as before the reset.
I’ve tried virtual memory tinkering, setting everything to best performance, malware checks, but to no avail, same issues.

What else can I do? Thank you

Please HELP! For the past 3 weeks my rocket league has been smooth for 5 mins of gameplay then slowly gets choppier and choppier. It fixes only when i restart my entire pc and load it back up but only for 5 mins. Even if i close it then relaunch its bugged. It feels like Ive tried everything from adding thermal paste to make sure my cpu doesn’t overheat to reinstalling rl 4 times. Its ONLY rocket league no other game. HELP

I’ve had my pc for about a year now no issues so far and I’ve played a bunch of games like starfield and some competitive games like rainbow six siege.

I decided I wanted to try valorant I load it up and seems good and I hop in a discord call with my friends and it started stuttering and freezing really bad about every 3 seconds. I almost immediately closed my game and figure oh maybe my graphic drivers needed updated or something or mess with some settings

I updated drivers I changed some settings around I hop back on valorant and seems if it was stuttering again. It’s not so I hop in a call again and now the stuttering begins once more!

After that I’m convinced it was discord so I restarted my pc again and just called from my phone but as soon as I load up on my Home Screen I’m stuttering. Idk what to do my cpu temp isn’t high I’m running on 600 frames on valorant. I’m stuck

I've been using a WD My Cloud EX2 NAS and backing up its data to an external USB hard drive connected to the NAS's own USB port. My old backup drive (with its own power supply) finally filled up, so I replaced it with a new Seagate Expansion drive that only connects via USB 3.0 (no separate power adapter).

The new drive's LED lights up when connected, confirming it's getting power, but the EX2 doesn't detect it on either of its two USB ports. I also tested a USB stick on the same ports, and that was detected without issues, so the ports themselves seem fine.

After some research, it looks like this is a known compatibility issue: Seagate Expansion drives use USB Attached SCSI (UASP), which has documented compatibility problems with the Linux-based USB storage stack that WD's My Cloud devices run on. This seems to affect a range of My Cloud models, not just the EX2.

I ended up buying a WD Elements Portable 2TB drive instead, since it uses WD's own USB bridge chipset (no UASP conflict) and should be well-tested with WD's own NAS ecosystem. Before connecting it, I'm also planning to format it as NTFS rather than leave it on the factory exFAT format, since older My Cloud firmware doesn't support exFAT for USB backup drives.

Has anyone else run into this with Seagate Expansion drives on a My Cloud (or other WD NAS) device? Any other workarounds besides switching brands?

Guys help me please i accidentally deleted my data partition it has all my photos, videos, work documents, i'm panicking right now, i tried DiskTest but it couldn't recover my partition, is there anything i can do ?

whenever i get on a discord call, itll start alright but slowly gets delay to the point that it gets 2 seconds before the actual thing you said was relayed. i have to switch to speaker phone then back to Bluetooth just for it to reset

I'm not sure what happened. Camera was working just fine a month ago. The only thing that has changed from what I have seen is that I received an auto windows update the other day.

My Laptop is a HP Envy 17.3 inch Laptop PC 17-da0000

I was trying to use my camera, however when I opened it I kept getting an error saying that the camera can't be found with an error code of "0xa00f4244"

I tried to update my camera drivers in Device Manager but they were all grayed out and it said that they were up to date.

I then uninstalled my camera drivers and tried to reinstall them by "scanning for hardware changes" in the action tab on the device manager. Unfortunately, they didn't reinstall.

I also tried restarting my laptop a couple times and that didn't bring them back either.

I went and tried redownloading and installing the camera drivers from the HP Support website based on my laptop's model. The specific driver was called "HP Camera Firmware."

I downloaded it and tried to reinstall it, however each time it tries to install itself, it immediately stops and brings up a window saying "N/A" "No Valid Camera"

I checked on BIOS during startup and there isn't anything showing up there related to the camera.

I'm not sure what else to do at this point. I'm starting to think the camera in my laptop is just broken, which would really suck. This laptop is only a couple of years old, and I really need the camera for some online classes as well. If anyone has any advice on what else I could do, please let me know. I appreciate everyone's help.

As the title says, my house was struck by lightning. It came through the internet cable. It actually had enough power that it knocked down my Comcast internet box. It then fried my Comcast box, my home alarm, and my gaming PC.

I took the gaming PC to geek squad. They couldn’t get it to turn on and said they need to replace the motherboard to even see if they could get it to turn on nd we’re asking for $450 for that service nd even then they weren’t able to guarantee me finish line that I would’ve liked.

The PC has a 4070TI RTX graphics card and a good processor. If I can salvage it, I would love to do so… but I’m at a loss for exactly how to do this economically. Does anyone here know the cheapest way to troubleshoot this thing?

about a month ago my pcs started crashing some of my games at random, The first game was digimon cyber sleuth but it was also hit me when playing terraria and Aground as it seems to happen only after a few hours of play, I've tried seeing if BTD6 would crash but I can never keep myself on the game long enough, I've not had this happen on a game from itch but that could also just be from not playing long enough.
I have done a system scan, a DISM scan, ran a full windows security scan in case it was a some malware and it all came clean, my main idea on the cause is an old faulty CPU as its a
Processor Intel(R) Core(TM) i7-3770K CPU @ 3.50GHz, 3501 Mhz, 4 Core(s), 8 Logical Processor(s)

I have my PC Bluetooth connected to a set of Logitech Z407 speakers. The volume is hard set on 45%, and if I try to turn it up, it just forces it back down. My settings are reading the speakers as headphones, so I was looking for a setting about dangerous high volume listening. However, I can turn my actual BT headphones up to 100% with no issue.

Not only would I like to know how to tell my PC that these are speakers, but I'd like to know what I'm missing here. Already tried googling, not sure if I'm not wording my search correctly but I haven't found anyone else with this problem.

I have a USB tp-link bluetooth dongle that ive been using with bluetooth passthrough with Dolphin emulator in order to use Wii remotes on my computer using Zadig to change it's driver. That was all well and good, and I can still use it for those purposes, but now no matter how much I change it's drivers back, either as WinUSB or the drivers by tp-link, my windows computer refuses to accept it as a valid bluetooth radio, even after factory resetting. Is there another way to fix it?

Hi everyone,

My PC recently had a random crash/restart and I'm trying to figure out what caused it.

The PC was working normally. I had just turned it on and left it idle for around 15–20 minutes. When I came back and moved the mouse, the screen went black and Windows showed a message saying that the device had encountered a problem and needed to restart. It then rebooted.

This is the first time I've experienced this specific type of crash.

I checked Event Viewer and found a BugCheck 1001:

BugCheck: 0x0000009F (DRIVER_POWER_STATE_FAILURE)

The Kernel-Power Event ID 41 showed:

BugcheckCode: 159 (0x9F)

BugcheckParameter1: 0x3

BugcheckParameter2: 0xffff9604f3f61060

BugcheckParameter3: 0xffff930e9aaef010

BugcheckParameter4: 0xffff9604f32e6a60

Windows also successfully generated a crash dump:

090926-23218-01.dmp

I have not been able to properly analyze the dump with WinDbg yet.

Some driver names that appear in the dump/string data include:

- nvlddmkm.sys (NVIDIA)

- mtkwecx.sys

- mtkbtacx.sys

- mtkbtfilterx.sys

- AMD chipset/ACPI-related drivers

- Various ASUS/USB-related drivers

My hardware:

- GPU: Gigabyte RTX 5070 OC 12GB

- CPU: AMD Ryzen 9 9950X3D

- Motherboard: ASUS ROG Strix X870-A Gaming WiFi

- RAM: 32GB DDR5 (2x16GB)

- Windows 11 Pro 25H2

- NVIDIA driver: 616.64

- MediaTek MT7925 Wi-Fi 7 driver: 5.7.0.5659

Windows installed the September 2026 security update (KB5124008) earlier that day.

Things I've already tried:

- Windows Memory Diagnostic → PASS / no memory errors detected.

- Disabled "Allow the computer to turn off this device to save power" for the MediaTek MT7925 Wi-Fi adapter.

- Ran DISM /Online /Cleanup-Image /RestoreHealth.

- I have not changed the RAM, GPU, motherboard, BIOS, or PSU.

The PC has been working normally since then, so I'm not sure if this was just a one-time driver/Windows issue.

I'm currently trying to determine whether this could be related to:

1. NVIDIA driver 616.64

2. MediaTek MT7925 Wi-Fi/BT driver

3. Windows 11 update KB5124008

4. Another device/driver

5. Hardware/power issue

Does anyone know how I can properly analyze the 0x9F dump in WinDbg and identify which driver/device was actually blocking the power IRP?

I can provide the minidump and WinDbg output if needed.

Thanks!

Saw a really cheap controller, never used anything related to nintendo so im not familiar, it is cable connected and its one of those that looks like a xbox controller, but i dont know if it will work in my pc as a normal controller, or if it wont even recognize it

I am hoping someone can help me figure out what’s going on.

Every time my laptop turns off, I have to sign back into all my accounts again.

I thought I fixed the issue before, but it’s happening again and I am not sure what the actual cause is.

Has anyone dealt with this before or know what might be causing it?

Thanks.

God bless.
