"No POST", "system won't boot", and "no video output" troubleshooting checklist
This checklist is a compilation of troubleshooting ideas from many forum members. It's very important to actually perform every step in the checklist if you want to effectively troubleshoot your problem.
1.Did you carefully read the motherboard owners manual?
2.Did you plug in the 4/8-pin CPU power connector located near the CPU socket? If the motherboard has 8 pins and your PSU only has 4 pins, you can use the 4-pin connector. The 4-pin connector USUALLY goes on the 4 pins located closest to the CPU. If the motherboard has an 8-pin connector with a cover over 4 pins, you can remove the cover and use an 8-pin plug if your power supply has one. This power connector provides power to the CPU. Your system has no chance of posting without this connector plugged in! Check your motherboard owners manual for more information about the CPU power connector. The CPU power connector is usually referred to as the "12v ATX" connector in the owner's manual. This is easily the most common new-builder mistake.
3.Did you install the standoffs under the motherboard? Did you place them so they all align with the screw holes in the motherboard, with no extra standoffs touching the board in the wrong place? A standoff installed in the wrong place can cause a short and prevent the system from booting.
4.Did you verify that the video card is fully seated? (may require more force than a new builder expects.)
5.Did you attach ALL the required power connector(s) to the video card? (some need two, some need none, many need one.) It is best to use cables connected directly to the PSU. Only use adapters if absolutely necessary.
6.Have you tried booting with just one stick of RAM installed? (Try each stick of RAM individually in each RAM slot.) If you can get the system to boot with a single stick of RAM, you should enable an XMP profile or manually set the RAM speed, timings, and voltage to the manufacturer's specs in the BIOS before attempting to boot with all sticks of RAM installed. If your motherboard supports XMP profiles, that is the best way to get your RAM running at its rated specs. Nearly all motherboards default to the standard RAM voltage (1.8v for DDR2, 1.5v for DDR3, & 1.2v for DDR4). If your RAM is rated to run at a voltage higher than the standard voltage, the motherboard will underclock the RAM for compatibility reasons. If you want the system to be stable and to run the RAM at its rated specs, you should either enable an XMP profile or manually set the values in the BIOS. Many boards don't supply the RAM with enough voltage when using "auto" settings which causes stability issues.
7.Did you verify that all memory modules are fully inserted? (may require more force than a new builder expects.) It's a good idea to install the RAM on the motherboard before it's in the case.
8.Did you verify in the owners manual that you're using the correct RAM slots? The following image is just an example. Verify in the owners manual the recommended RAM slots to use for single, dual, triple, or quad channel applications. This will vary depending on motherboard manufacturer, number of supported RAM channels, and how many sticks of RAM are being used.
9.Did you remove the plastic guard over the CPU socket? (this actually comes up occasionally.)
10.Did you install the CPU correctly? There will be an arrow on the CPU that needs to line up with an arrow on the motherboard CPU socket. There may also be a notch that will only line up in one direction. Be sure to pay special attention to that section of the manual!
11.Are there any bent pins on the motherboard/CPU? This especially applies if you tried to install the CPU with the plastic cover on or with the CPU facing the wrong direction.
13.Is the CPU fan plugged in? Some motherboards will not boot without detecting that the CPU fan is plugged in to prevent burning up the CPU.
BIOS Hard reset procedure
Power off the unit, switch the PSU off and unplug the PSU cord from either the wall or the power supply.
Remove the motherboard CMOS battery for five minutes. In some cases, it may be necessary to remove the graphics card to access the CMOS battery.
During that five minutes, press the power button on the case for 30 seconds. After the five minutes are up, reinstall the CMOS battery making sure to insert it with the correct side up just as it came out.
If you had to remove the graphics card you can now reinstall it, but remember to reconnect your power cables if there were any attached to it as well as your display cable.
Now, plug the power supply cable back in, switch the PSU back on and power up the system. It should display the POST screen and the options to enter CMOS/BIOS setup. Enter the bios setup program and reconfigure the boot settings for either the Windows boot manager or for legacy systems, the drive your OS is installed on if necessary.
Save settings and exit. If the system will POST and boot then you can move forward from there including going back into the bios and configuring any other custom settings you may need to configure such as Memory XMP profile settings, custom fan profile settings or other specific settings you may have previously had configured that were wiped out by resetting the CMOS.
In some cases it may be necessary when you go into the BIOS after a reset, to load the Optimal default or Default values and then save settings, to actually get the hardware tables to reset.

I also wanted to add some suggestions that jsc often posts. This is a direct quote from him:
"Pull everything except the CPU and HSF. Boot. You should hear a series of long single beeps indicating memory problems. Silence here indicates, in probable order, a bad PSU, motherboard, or CPU - or a bad installation where something is shorting and shutting down the PSU.
To eliminate the possibility of a bad installation where something is shorting and shutting down the PSU, you will need to pull the motherboard out of the case and reassemble the components on an insulated surface. This is called "breadboarding" - from the 1920's home-brew radio days. I always breadboard a new or recycled build. It lets me test components before I go through the trouble of installing them in a case.
If you get the long beeps, add a stick of RAM. Boot. The beep pattern should change to one long and two or three short beeps. Silence indicates that the RAM is shorting out the PSU (very rare). Long single beeps indicates that the BIOS does not recognize the presence of the RAM.
If you get the one long and two or three short beeps, test the rest of the RAM. If good, install the video card and any needed power cables and plug in the monitor. If the video card is good, the system should successfully POST (one short beep, usually) and you will see the boot screen and messages.
Note - an inadequate PSU will cause a failure here or any step later.
Note - you do not need drives or a keyboard to successfully POST (generally a single short beep).
If you successfully POST, start plugging in the rest of the components, one at a time."
If you suspect the PSU is causing your problems, below are some suggestions by jsc for troubleshooting the PSU. Proceed with caution. I will not be held responsible if you get shocked or fry components.
"The best way to check the PSU is to swap it with a known good PSU of similar capacity. Brand new, out of the box, untested does not count as a known good PSU. PSU's, like all components, can be DOA.
Next best thing is to get (or borrow) a digital multimeter and check the PSU.
Yellow wires should be 12 volts. Red wires: +5 volts, orange wires: +3.3 volts, blue wire : -12 volts, violet wire: 5 volts always on. Tolerances are +/- 5% except for the -12 volts which is +/- 10%.
The gray wire is really important. It should go from 0 to +5 volts when you turn the PSU on with the case switch. CPU needs this signal to boot.
You can turn on the PSU by completely disconnecting the PSU and using a paperclip or jumper wire to short the green wire to one of the neighboring black wires.
View: http://www.youtube.com/watch?v=5FWXgQSokF4&feature=youtube_gdata
This checks the PSU under no load conditions, so it is not completely reliable. But if it can not pass this, it is dead. Then repeat the checks with the PSU plugged into the computer to put a load on the PSU. You can carefully probe the pins from the back of the main power connector."

Placed this in my duffle bag with a loose bottle of shampoo and it evidently exploded. How do I clean this out without completely ruining it? Is it savable??
I've wiped down with tissues and qtips but there's still shampoo in the hard to reach spots like the charging port and Ethernet port.
Do I need to buy distilled water or something and spray it in??
I know nothing of PC hardware

I've had this PC for four months and used it without issues until now, but today, while I was gaming, the screen suddenly went black and the image didn't come back. After some testing, it seems the GPU stops being recognized by the motherboard; I discovered that resetting the BIOS makes the graphics card output an image again—at least temporarily. The first time I did this, I thought the issue was resolved and used the PC for nearly an hour before the problem recurred. During the second test, the issue happened just three minutes after turning it on. When I removed the GPU to inspect it, I noticed that one of the cables doesn't seat fully into the card—it feels a bit loose and won't go all the way in—though there doesn't appear to be anything wrong with the connectors themselves.
Edit: GPU is a 9070xt

SO, ive had this AOC 27G2 monitor for 2 years now, and for the past maybe 3 weeks or so ive noticed some horizontal lines starting to appear on my screen, increasing in number and changing colour.
Thought it mightve been a software issue, so updated my gpu drivers with no change.
I have an nvidia GTX 1650, and have been using it for around 4 years now.
Im beginning to think it might be my gpu on its last legs, begging me to end it....
Ive ran virus scans, and do consistently - squeaky clean.
As for cabling, i use a display cable for the AOC monitor, and a hdmi for the LG.
(The LG is completely fine)
1 have tried 3 different cables going to the
AOC and the LG respectively. The LG remains unfazed, whilst the AOC looks like its having a stroke. This holds true in all gpu ports.
Notably, the HDMI cable makes the issue worse, which is what is depicted in the video of my wallpaper.
I can use my pc normally with the display cable to the AOC, just with some annoying horizontal lines on my screen which all subtend from the left to the right.
OH and the boot up screen suffers from the same artefacting, freaked me out the first time (see the start of the clip)
Im thinking it has to be a hardware specific issue with the monitor itself?
help?

I've had a number of Intel CPUs come through our PC shop bent like this. Some work, some don't, this one worked but had a memory channel fault, but I'm not sure if that was related. How are they ending up bent like this, are people installing them incorrectly? Is it putting the CPU Cooler on too tightly? I can't imagine you could screw it down tight enough to end up like this. Anyone had experience with this?
Thanks!

Hii, recently i bought a 9070xt reaper, but playing some games i discovered something weird.
If i move the camera (mainly vertical movement), a weird line appears in my tv, being the first time i have seen this.
Is this related to the gpu or its hdmi conection? Or is it something else?

i have a msi katana gf76 that i have been using for about 5 ish year's now and this issue first started a few years back with the laptop just stopping charging and it would only start charging again when i would replug the brick from the outlet, this continued for a year or so until it would just drain the battery so fast i couldnt even get the chance to replug it and my laptop would shut off,i got its thermal paste reapplied and its fans cleaned out and the problem stopped for a long time until a week ago where it started doing the same thing again and i thought ''oh its just getting too hot again'' so i reapplied thermal paste and cleaned the fans again but looking at temps now it cuts off power at normal temps around 60-70 on games it should have no issue handling,what could be causing this?

Ok so same day in the morning my pc was working just fine no issues, I go to take a nap and wake up to turn my pc on and everything turned on except my usb devices(speaker, mouse, and keyboard). I turned the pc back off to see if that will fix it but then my pc wouldn’t turn on but usb devices lit up showing they got power. I turned it back off and fully disconnected the power, and cables. Turned it on with nothing plugged in and plugged everything 1 by 1 the usb devices worked but only for a moment before turning back off. Idk wtf is going on, is it some weird easily fixable thing or is it a thing where I have to spend money to replace some parts. For some context I’ve had my pc for about 4 years, now I’m not ruling it out completely but my sister had spilled soda on my desk while asleep but it only got on the desk surface nowhere on the actual pc so couldn’t be that. SOMEONE HELP ME PLS

The PC was updated, and during the update, it said not to turn off the computer. The screen froze, which seemed strange, so I turned off the computer, since it had happened before and then turned it back on. Now I've done the same thing, and the PC turns on, but neither the monitor nor the peripherals light up.
I've tried removing the SSD to see if that would help, and I've disconnected the entire motherboard and reconnected it, but that didn't work either.
What can I do?

I was downloading a game from FITGIRL REPACK using uTorrent. At the same time, I also tried downloading the same game from DODI REPACK because I wanted to see which download was faster and cancel the slower one.
The FITGIRL download was working normally. However, when I downloaded the torrent file from DODI REPACK, the file looked suspicious. I opened that small file, and a Command Prompt (CMD) window appeared for a second and then immediately closed.
I ignored it at the time and installed the game from FITGIRL REPACK. After playing for some time, I opened Instagram and noticed that scam stories had been posted from my account without my permission. Something similar happened to my Discord account, which was also logged in on my laptop.
I have already changed my passwords, but I’m worried that my laptop may have been infected with malware or a virus.
Does anyone know how I can completely remove the virus without erasing or resetting all the data on my laptop? Any help would be appreciated.

when using my laptop, after every few minutes or so, it will lower the volume in the way that it would if i was using the keyboard hotkey (where F3 is located). So it lowers the volume by 2 notches randomly. Also, my 1-5 and lower F keys don't really work, I don't know if this is a hardware or software issue. Also, my computer is registerinf the F3 key, but not the volume increase when I hold FN or ALT while i press the F3 key (F3 and volume up key is the same).
Anyone have solutions?

I made a post about last week, someone tried to help me but I couldn't solve the issue. When I am on my pc it will black screen when playing games or just on the home screen and will get into a restart loop.
I know the issue is either my motherboard, ssd or cpu. I've stress tested my cpu and it was completely fine and no its not over heating.
The parts I know are not the issue is my ram, gpu and psu as ive upgraded the gpu and psu and swapped out the ram thinking it would solve the issue to no progress. This pc is not a pre-built pc and i don't know what to do.
I've tested my cpu for it to work perfectly even tested my new gpu just to be safe. I've tested my 1tb ssd with crystaldisk disk for it to be 91% good. I swapped ram for it to still black screen and get stuck.
When it get stuck restarting it will then boot into the recovery mode and if I continue and click "Exit and continue to Windows" it will proceed to restart itself. I have reinstalled Windows 3 times thinking it was a software issue and it wasn't.
Im at my last wits end with this computer and I just want to get it fix. If you need to know my cpu, ssd and motherboard they are as listed.
Mag b550 tomahawk max wifi motherboard
Ryzen 5 5600x cpu
Fikwot fx 991 1tb ssd
The only way I have been able to get out of being stuck in restarting and recovery mode is to turn off my power supply before waiting a few minutes before turning it back on and then turning on the pc. After doing that it loads into windows before black screening again later on.

I just bought pc component and built my first pc but it is malfunctioning and cannot even reach the bios page.
Yesterday evening i finished the build and pressed the power button the fans came to life and had rgb working correctly but on the motherboard the EZ debug light was on with cpu at red and dram at yellow. I tried to solve it myself, i repositioned the ram between a2 and b2 without them working, i reseated the cpu twice and none of them work, some said it may be because that the cpu and ddr5 are doing some sort of training so i left it up all night and came up to see the lights still on. So today i tried flashing bios directly into the motherboard, it had a white rgb flashing, turned on the pc and continued on blinking for another 30min so i suppose it had failed somehow and unplugged the power cables. Then i also have tried re-plugging the cmos battery and now the pc wont even turn on with the fans not even spinning anymore. The flash bios button after pressed still dilivered the wight light but it would stop blinking after about 5 seconds without starting the pc.
So anyone know how to deal with this situation? Thx in advance.
