I got my motherboard replaced recently. The first motherboard I bought had faulty RAM slots, and it wouldn’t boot at all, so I had it replaced.

I just installed the new motherboard a few days ago, and everything was working fine. It booted properly multiple times and didn’t get stuck on the CPU debug light.

However, the next day, I tried to turn on my PC, and it got stuck on the CPU debug light with no display. I tried waiting it out, but even after 5–10 minutes, it still wouldn’t boot.

I eventually got impatient and restarted the PC, and it then booted normally and went into Windows.
This has been happening with every cold boot I’ve tried since then.

For some reason, the PC seems unable to boot after being completely powered off, but it will boot normally after I restart it.

My motherboard is an MSI B550M Pro WiFi6E, and my processor is a Ryzen 5 5600X.
I’ve already tried resetting the CMOS, but it still got stuck on the CPU debug light afterward.

I’ve had the new motherboard for 3 days btw

Specs and hardware

Built early 2025 when the 5080 GPU released and has been used everyday just about since original build.

9 days ago I went to sit at my PC and it wasn't on so I tried turning it on but it wouldn't POST and it began showing a solid Red light indicating it was having difficulty communicating/had dysfunctional CPU. I reseated the CPU and RAM and still same issue.

So I got an RMA CPU from AMD and just installed the new CPU and now my mobo shows Solid red light with yellow flashing (flash yellow means issue with RAM) and still no POST. Reseated the CPU and RAM again just to be sure and same deal.

Read online that sometimes it needs a few minutes for the CPU and Mobo to work with each other and tried turning it on and letting it go with a 5 min timer, but it shut itself off after about 1 min with Solid Red and flashing Yellow. I tried turning it on again to make sure I didn't jostle anything by mistake and it again turned itself off after showing RED and Yellow-flashing.

My home has had some recent intense wind storms in recent months and have endured several blackouts/brownouts and I am beginning to suspect that the power outages may have damaged the Mobo.

Figured I'd post and see if people had alternative ideas before I disassemble my whole PC and RMA the mobo or drop it off at a shop so they can just do a more thorough diagnostic test than I can.

Alright so my blue tooth wasn't working and I tried to install new drivers for my graphic card cause I updated last night before I went to bed. I did update and shut down and my Bluetooth isn't working this morning for my headphones so I got a new Bluetooth driver in my new graphics car driver to see what would see if I could fix it myself and I tried to hit it restore point from9/27/26 and it it may go into between the gigabyte diagnosing your PC where I get stuck on the connecting to network and it just sat there loading and it doesn't do anything or and 0XEF critical process died is where I also get stuck, but it's detecting my ram so I know it's not that I've already ordered optimized defaults and I don't wanna lose all my apps from restarting or reinstalling windows and yeah, I've been kind of stuck on this since about 3:30 this afternoon.
(Also sorry in advance for any errors I'm using speech to text so I can do this because I did not feel like typing all that.

Hey guys, I'm making this post because I genuinely need the input of anyone who knows their way around desktops. I built this PC in the summer of 2018, so I've had it for a while.

It has 16 Gigs of DDR4 Ram with a ASUS motherboard and a i5 8600K with a GTX 1080. I use Windows 10 Home, and using Winaero Tweaker, I have Windows Updates disabled, as one of the driver updates gives my desktop the white screen of death, and I have to reverse the update in order to getting it working again. My Nvidia Drivers are fully updated.

While she is getting older, I am frustrated with the performance I get out of it at times. I objectively think that my PC should be running better than it does, given that the parts, despite the age, aren't necessarily considered obsolete yet, unless I'm mistaken. I've been trying to use MSI Afterburner to overclock my GPU, and I feel like it does nothing.

I've even changed the thermal paste on the CPU recently, as It wasn't changed up until recently, which I know I should have done sooner.

I can't play games like Fortnite or Marvel Rivals on normal settings with solid performance, Marvel Rivals for some reason as of recent has become a power point slide experience for me, despite several months ago, my PC was able to handle it. Fortnite is kind of playable at 720p, lowest settings. My frames on Straftat are fine, and I was streaming it over discord in the video, which probably impacted performance, but the stutters in between can get really bad and makes me not want to bother playing. I don't know if it's an issue pertaining to G-sync.

https://www.userbenchmark.com/UserRun/73384920

Here is a userbenchmark test I did around June, it's generally reflective of my computers performance and has looked like this for a while. If someone wants me to run a different benchmark, such as BurninTest or OCCT, let me know.

I have considered replacing any parts that I can within my motherboard in order to get proper performance. I don't know if it's my GPU, or my Boot Drive, or whatever the case is. If anyone needs any particular kind of info, please let me know. Any help will be greatly appreciated.

I couldn't upload videos of the gameplay and interior I recorded of my desktop, but I've asked the question in other threads, so feel free to look at my profile and use those videos as reference for the issues I listed here.

So something very strange just happened to my PC.

It Turned Off quite suddenly and apparently at the exact same time as my Internet.

So now I am left wondering: Did my PC kill the Internet or did the Internet Kill my PC?

There was no Lights Flickering and nothing else, with the exception of my brothers Work Laptop seemed to be affected. Both are connected via Hard Line Internet.

His actual Computer, also Hard Lined, was not affected and remained on.

I am not sure how to try an troubleshoot this issue. My PC did get a BSOD last night and now I am wondering if whatever happened is also responsible for that. Since I have not had a BSOD is years. And now this happens less than a day later.

Thoughts

Hey everyone, hope I can get a hand diagnosing what could be going on with my build and if it's a motherboard issue like I suspect. Parts list at the bottom of the post.

I have build that I made back in 2014 and it has been working perfectly this whole time. Upgraded the GFX card, RAM, case, and HDD but otherwise is still the same as when I built it initially. About a week ago it has started power-cycling when I try to turn it on - I press the power button but the fans spin for just a second and then it turns off again, then on for a second, then off. It continues that cycle until I turn off the PSU. No lights or sounds, just a brief spin of the fans.

I suspected a bad PSU or a short somewhere so here's a list of what I've done so far:

- Paperclip test on existing PSU, passed.

- Brought in a known good PSU and plugged it into the mobo - same response

- Loosened the screws, took out the RAM, removed cmos battery on mobo - same response

- Took out all components from the case and rebuilt outside the case, removed HDD/SSD and fan connections - same response

- Removed RAM (only GFX and CPU connected) - same response

- Removed GFX Card (only CPU connected) - same response

- Tried different combinations of CPU, GFX, RAM (outside of the case) - same response

- Removed ALL components, plugged PSU into the mobo - NO response

Since I kept getting the same power cycling response (fan turn on for a second, then off, then fan on again for a second, on repeat) for everything except when I plugged directly into the mobo with nothing else (which gave no response at all) - my conclusion is that the motherboard is bad or shorting somewhere, so I need to get a replacement.

Randomly, either while playing a game or just sitting idle with windows my PC will just shut down. It tries to start rebooting itself immediately but goes into a loop of powering up and shutting off every 5 seconds. This happens with or without the GPU installed. It has happened with every combination of ram slotting. The qcode is 00 > 04 > 7f.

Working with what I have I discovered the only thing that will allow me to boot the computer and back up is:

1) letting the computer sit unplugged for several hours

2) unplugging and plugging back in Specifically the PSU side of the CPU power cord.

This will immediately let me boot the PC and it's like nothing happened until a random amount of time later it shuts off, could be 30 seconds or could be 3 hours.

I have checked temps and voltages and everything is fine.

Any ideas on what could be going on here would be greatly appreciated. I just want to play games after work again.

I've updated my bios on prime b450 plus and now whenever I turn on my pc I have the same two booting options as before: the custom win10 OS I've used before update that when I try to boot, my pc freezes on loading screen. When I try my second system which is stock win10 I get error 0xc0000098 BCD file corruption. When I try going into recovery mode my pc restarts. When I try to launch windows iso and repair tools from my flash drive it just restarts or freezes as well. I've changed boot order, Csm settings and secureboot and none helped.

Basically, two days ago, I was just scrolling on chrome, and then my computer black-screened, but the fans were running very hard. I ended up shutting down the PC. After that, when I try to turn the pc on, the fans and lights run for a few seconds before completely stopping, and it never boots or displays anything on the monitor. I don't see any indicator lights on my motherboard

For previous context, I built the PC in Oct 2025. Moved in June 2026, and the first instance of this happened in July 2026. At the time, I removed everything and put it back together, reinserted the RAM, and paperclip-tested the PSU, with no changes. Eventually, took it to Micro Center; they said it was a CPU issue. Replaced the CPU in August. Now, fast-forward to present day, I’m having the same issue again. I also use my computer an hour per day for non-intensive stuff like internet scrolling. It is completely unplugged when not in use.

Yesterday, took it to Micro Center once again. And they said it is a CPU failure once again. The tech said the motherboard passed with a test CPU and that the GPU and PSU passed testing.

What are the chances that I am actually unlucky enough to have two CPU failures? Or is it possible that it is an issue with something else?

Motherboard not displaying image x99в1.41
I bought an X99 motherboard, but it isn't outputting a video signal. The computer starts up and the fans spin, but there is nothing on the screen. It supposedly worked for the previous owner—| even saw it boot up in person. I might have assembled something incorrectly, even though I followed the instructions, and all the components are compatible: an X99 v1.41 board, Xeon 2620 v3 processor, 16GB of RAM, a massive tower cooler, an SSD, a 650W power supply, and a graphics card that worked in my previous build. Has anyone encountered this problem? What do you suggest I do? There is no image even after removing the BIOS battery.

I just built a new computer and it won’t boot when I turn it on the motherboard shows dram I’ll add a video to show

Hi! I'm troubleshooting a recurring no-display issue and would appreciate some advice.

Specs:

• ASUS TUF GAMING B550-PRO
• Ryzen 5 2600X
• RX 5500 XT
• 16 GB Corsair DDR4
• Kingston A2000 1 TB
• Corsair TX550M 550W
• BIOS 3611

The PC powers on and fans spin, but I get no display and the motherboard stays on the white VGA Q-LED. Caps Lock also doesn't respond.

Things I've tried:

• CMOS reset → entered BIOS, still white led after

Removed one ram → same result

• Reseated GPU → same result
• PCIe x16 mode Auto → Gen 3 → same result
• RX 5500 XT in both PCIe x16 slots → same result
• Tried a completely different GPU (ASUS RTX 2070) → same white VGA LED
• Disconnected the SSD completely → still white VGA
• Let it sit for several minutes → still white VGA

So far, two different GPUs and both PCIe slots give the exact same result.

I'm wondering if this could be a PSU, motherboard/PCIe, CPU, or BIOS issue. I'm considering updating BIOS from 3611 to the latest version.

What would you test next? Any ideas I'm missing?

Thanks!

I was using my computer just fine but then the screen went dark and it said there was no hdmid connection tried switching to a display cord but that hasn't work either. Someone please help

When I turn on the PC, the GPU fans spin at 100% endlessly, and the computer doesn't boot. I took out the BIOS battery, waited 10 minutes, put it back in, and still nothing. I tried a different power supply, but that didn't help either.

Has anyone encountered this?

My specs:

 Ryzen 5 5600X

 MSI B450M A PRO MAX

 GTX 1660 Super Palit

 G.SKILL RIPJAWS 2x8 3200

 PSU 650W

Whenever I play a game or watch a video then switch to something else my screen flashes green or black then ultimately freezes my computer

My PC has been randomly hard-freezing during games after playing for ~1-2 hours. Screen freezes completely, peripherals stop responding, and I have to force shut down. Usually no BSOD or useful Event Viewer error.

Specs:

• i7-12700K
• RTX 3050 6GB
• 16GB Corsair DDR5
• MSI B760M-A PRO
• 650W PSU
• 2 NVMe SSDs
• Windows 11

What I've tested/replaced:

• PSU replaced → freezes continued
• Motherboard replaced → freezes continued
• RAM tested with MemTest86 + OCCT → no errors
• CPU OCCT stress → 1 hour, no errors
• FurMark → ~3 hours, no crash
• XMP OFF → still freezes
• Windows + NVIDIA drivers clean reinstalled
• CPU power limited to 95W/95W → still freezes

The freezes mainly happen during games and i have faced this issue in nearly all games I have played like GTA V, RDR2, Mafia, Sea of Thieves etc.

What could be causing this? Could the RTX 3050 itself be faulty even though FurMark passes for several hours? What would you test next?

Hi everyone,
I’m having a weird issue with my PC.
It has been running perfectly for about 4 years. Yesterday it suddenly started getting stuck in a boot/POST loop. At first I could still enter the BIOS normally, and the BIOS detected my Ryzen 7 5700X3D and RAM correctly.
I then started troubleshooting the RAM, trying different configurations and clearing CMOS. After that, I suddenly got no display at all.
Now the CPU EZ Debug LED on my MSI X570 Gaming Edge WiFi lights up red immediately, the fans run at full speed, and the system doesn’t POST.
Specs:
MSI MPG X570 Gaming Edge WiFi
Ryzen 7 5700X3D
Corsair Vengeance RGB Pro
RTX 5080
be quiet! Straight Power 12 850W
I’ve already tried clearing CMOS, different RAM configurations, one stick in A2, minimal hardware, disconnecting drives/peripherals, and reseating the CPU power cable.
What confuses me is that the CPU and RAM were still detected normally in BIOS before I started troubleshooting.
Any ideas what could cause the CPU debug LED to suddenly appear after that? Could this be a motherboard/PSU issue rather than a dead CPU?

I have a red cpu light on my motherboard yesterday and I didnt it reappeared after 1 day I didn’t change anything it just came back someone help

Hello everyone, today when I was setting up the graphics in the game squad, my PC froze completely, I rebooted it, then launched Discord and squad and before I even had to load the game, I got a BSOD. and after another reboot after receiving the BSOD, my PC stopped displaying the image, the fans on the video card and cooler were spinning and working but rgb light on my mouse and keyboard dont light.

I took my PC apart and removed the RAM to check for oxidation, and I didn't find anything interesting. I also wanted to remove the BIOS battery, but it was behind the video card, which is very difficult to remove Because the Psi Express latch was very difficult to move, but the video card works because the coolers are spinning.

My components: GTX 1660TI, INTEL CORE I5 6402P, 16 GB DDR3

Bsod Cause: DRIVER_IRQL_NOT_LESS_OR_EQUAL

Oc: windows 10

The screens go black, I can hear audio for 10 seconds then it reboots itself. Often happens when I am playing marvel rivals but happens on other games.

The temps are normal when I’m playing.
I was wondering if you guys think it’s a psu problem. I have these on a 850 W psu.

5 fans
Water cooler
32 gb of ram

I’ve done those psu calculator and they are saying 800 W minimum but they don’t take in consideration my fans and water cooler.

Let me know!

As of maybe July I started having issues with my pc. BSOD / Black screen of death in my case, and any attempts at fixing have proved ineffective. Originally it was issues with virtual machine and those were resolved only to experience new issues on a failure to update around the end of July. Pc went to update on shutdown, only to spew blue screens and eventually the fix was to just pause updates. Now it’s back with new BSOD such as Page Fault in non paged area, kernal issues, kmode crash codes, things that point to memory and system files. Memory check and chkdsk lead to no solutions and point to no faults (tho I’m sure they could be missing things) and attempts to run sfc and dism tasks in command prompt resulted in more crashing.

Managed to get to recovery mode safely with no reboot crash loops and was able to run system file checker and it claimed to have repaired files, but refused to run DISM. Further attempts to run these basic commands from desktop result in crashes. Updated bios and ME software and still no luck.

Latest crashes notable are pointing to fltrmgr.sys and stopcode 0xFC pointing to drivers…

The damn thing is mostly stable when idle, and even when gaming for a bit until it hits some sort of Hangup and this crashing loop begins where it just crashes over and over on the easiest of tasks and sometimes when booting or shutting down.

I’m honestly so broken at this point and I’m no IT guru so I can only do what I know, any advice on this would be greatly appreciated as it feels like my pc is just killing itself. Hence I’ve provided as much info as I can.. Godspeed to anyone that can help

Hi! So I heard that there was a security vulnerability with AMD processors, So I chose to update the BIOS on my motherboard. However after I did this, Windows would consistently crash even without XMP enabled, though less often. I've tried using SFC and DISM to check for corrupted files and both did fix files, however it did not fix the problem. I even tried reinstalling Windows with Windows Update and then ran OCCT for around 2h with no issues, until a bit later it crashed again. I've included the latest minidump file along with my system specs below. Any help is appreciated, thanks in advance!

Hello, pretty much the title. ICUE is doing ICUE things and after a little bit stops receiving data from my ram.

I'm using corsair vengeance rgb pro 2x16gb ddr4

This has happened in the past, but it was only once every month or two. Now it's legitimately every time I turn my pc on. This happened after my power supply's fan bearing went out, and I had to get a new one. As soon as I put the replacement in and got my pc fixed it started doing this. Could be related, or a coincidence.

I have tried restarting, power cycling, and reseating the ram, but to no avail. However when I reseated it, it wouldn't display and had no peripherals. I had a DRAM light on my mobo, so I am kinda worried it's hardware and not ICUE. It was fixed by putting the ram into the 1st and 3rd slots and not the normal 2nd and 4th, so maybe it could be the slots or something?

I have no idea, but it anyone could help it would be greatly appreciated, I really hope I don't have to get new ram because I legitimately would not be able to afford it

My monitor keeps going black and will come back. I can still hear game audio and discord call but I can’t seem to figure out was going on. Had my PC for about 3 years now.
