Question Computer reboots randomly ?

[rooks09]

Hello fellow techies!

This is a situation I have never encountered over the past 16 years I have been building. Basically, my monitor goes black and the PC acts like it restarts but the video doesn't come back on until I unplug everything and turn it back on. This can occur when I am sitting here browsing the web or when I am playing Warzone. The PC is still on and everything is still spinning. When the monitor goes black I look over at the motherboard and see the Q-codes rapidly changing from 14 and 15 which would point to CPU or RAM, according to ASUS's codes. Changed both. I have replaced the CPU, Motherboard, switched out RAM from another PC, new PSU, and swapped graphics cards with another PCI have in the house. I am out of ideas. I have also reinstalled windows, utilized DDU to install new graphics drivers, everything I can think of. Anyone have any ideas? Specs listed below.

PS: I understand that my RAM is not on my MB QVL...However, this system has been running flawlessly. It will be 3 years since build date in December and I have swapped memory modules with another set that is on the QVL. No overclocks on CPU or Memory.

Temps seems good as well using HWiNFO64

IDLE CPU 42.5C
IDLE GPU 39.8C
LOAD CPU 72.1C
LOAD CPU 70.7C

GPU Hot Spot Temp reads max temp of 107.4
Could this be something even though the GPU temp is still only reading 70.7?

Maybe there is something I am overlooking. Who knows lol. Thanks for reading if you got this far.

Specs:
Motherboard: Asus Crosshair Hero VIII
CPU: AMD Ryzen 5900x
GPU: Asus Rog Strix 3090
RAM: G-Skill F4-4000C16D-32GTRS
PSU: EVGA 1050 SuperNova 80+ Gold 1050w

Edit : Sometimes I can game for 4+ hours like last night. It crashed once at the beginning of the night, then never again. Woke up this morning. Starting browsing the web crashed within seconds. Has crashed 4 or 5 times over the course of 3 hours, whether gaming or browsing.

What power plan are you using for Windows?

What power plan are you using for Windows?

Currently, balanced. I was on performance and thought I'd try balanced...no change.

Perhaps it's some issue of hard disk? Or power supply?

This may be a lot of questions but they can all be relevant.

Do you have the latest Chipset drivers installed for your motherboard/CPU?
Are you on the latest BIOS for the motherboard?
Have you checked the PSU power plug on both ends to make sure it is firmly plugged in all the way?
Have you tried a different wall outlet?
Do you have a UPS being used with the PC?
Are there any other high power devices on the circuit that the PC is on?
What does windows event viewer say about the "shutdowns"?
Does your graphics card have a vBIOS switch? If so try the alternative vBIOS for the graphics card.
Have you looked for obvious shorts on the motherboard or any other components?
Have you tried building the PC outside of the case like a testbench?

Do you have the latest Chipset drivers installed for your motherboard/CPU? Yes one of the first things I tried.
Are you on the latest BIOS for the motherboard? Yes. Same as above.
Have you checked the PSU power plug on both ends to make sure it is firmly plugged in all the way? This. And went out and purchased a 1000 watt and 1300 watt gold+ just to make sure I had enough wattage for the system lol.
Have you tried a different wall outlet? This is my next step.
Do you have a UPS being used with the PC? No. Went and purchased a new power strip just to verify it wasn't my other one.
Are there any other high power devices on the circuit that the PC is on? My daughter has a PC on another wall. The only other thing plugged into the same outlet are my 2 monitors. This is why I was waiting to take it apart and move it to another room. The 2 PCs in the room have been running great for about 3 months, as we just moved. One day it just shut off. Her PC is running fine.
What does windows event viewer say about the "shutdowns"? Critical Events every time it shuts off due to power kernel 41 I believe. Going off memory. It says something about loss of power. Hence the 3 power supplies I tried.
Does your graphics card have a vBIOS switch? If so try the alternative vBIOS for the graphics card.
Have you looked for obvious shorts on the motherboard or any other components? Swapped out the motherboard with an RMA. Memory and graphics look fine. Tomorrow the plan is to take everything out of the case and try it again.
Have you tried building the PC outside of the case like a testbench? Test bench plan is tomorrow. I'll update with what happens. This whole situation has me dumb founded. Never ran into something like this. Appreciate the feedback! Keep it coming! Work has me all over so planning on tomorrow night tearing it all apart.

Same problem right here, PC was running fine then suddenly black screened, need to restart it manually by unplugging the PSU.
Restarted it 10 to 20 times, 10/20 times pc POST fine but rest of the time it does 1 long beep and 2 short beep (video card error).

Either way the PC boots into windows but when I start putting GPU under load, goes black screen and sometimes restart, sometimes does nothing, sometimes just goes back to normal but crashes what I was doing and end on the desktop.

Happened first to me yesterday night while I was watching a youtube video.
Tried to run 3DMark Benchmark demo, works fine on first step but does the black screen thing right after loading Graphics Test 1.

Tried to launch COD MW2, went into multiplayer, worked fine but as soon as I go back on 3DMark, it repeated the steps explained right above.

Actually did reseat the GPU, tried doing new driver, old drivers or no driver at all, nothing seems to work.
Tried with an old 1050 TI I had around, 3DMark was running fine and did not crash (didnt update the driver on the 1050 TI) Currently reseting the computer. As my second build it is my first time writing on here, kind of really scared and desperate about my GPU.


SPECS :
Moth : B550M Elite Aorus
CPU : Ryzen 7 5800x3d
GPU : 3080 FE

Hard disk is on the table to take a look at. They are m.2s. So removing them can be a bit of a pain. Gonna tear into it all tomorrow and try and find a fix. Thought u had it with the power supply when I purchased a new one. No luck. The part that gets me is that I can play for hours sometimes, 4k, ultra settings pulling around 100 fps with no issues. Other times I can't even scroll the web for 5 minutes before it just goes black. Computer still running. Motherboard just keeps trying to retrain the memory it looks like. Starting to think I have a dying cpu but I tried a 5800xd3 and it did the same thing...just lost lol

Does this happen in BIOS as well?

I'm having random restarting issues myself and have determined it happens in BIOS as well, which rules out Windows issues etc.

Yes left it on bios screen for about 10 minutes and it did it as well. I also installed a new version of windows 11 and did registry checks to make sure it wasn't something conflicting with windows.

Alright guys. I went ahead and purchased a new AIO because the one I had was about 5 years old so I said wth and changed it out for fun. Played Warzone for about 5 hours last night with the boys/wife....all good. This morning woke up and screen is black and it is sitting on the Q15 once again. Swapped outlets to verify it wasn't an outlet. Here's my thought process. I've swapped everything at this point. I'm thinking I'm an idiot and purchased a "Like New" MB from Amazon to replace the faulty one and this one is also faulty. Long shot but maybe lol. So I am returning the ASUS HERO VIII and I am running out to Best Buy in a little to pick up the only AM4 board they have which is the MSI B550 Gaming Plus. Will update as soon as I can. Fingers crossed........Dram light on...Q15...Won't boot now. Has to be a faulty motherboard right? I've put new memory and a new cpu in it and it still happens....ahhhh headaches.

Went out and purchased an MSI B550 MB yesterday. Said screw the $400 ASUS one, I'll just bite the bullet and get this one from Best Buy. Well to my surprise I get home swap everything out and the PC won't start. Everything would light up...Including the CPU LED...No post. So, pull everything out of the case and do a test bench build adding one thing at a time including taking another CPU and install it. Still nothing. Has to be the BIOS since I had the 5900x, right? Wrong. Doesn't work. Alright, start plugging everything one at a time for 6 hours turning it on and off. About 1AM I am toast and about to give up and the CPU light goes out. Start looking around and the only thing that I have left unplugged at this moment is the RESET Switch to the MB. Put it all together and leave it on overnight, no crashes. Beat the MW3 campaign today, no crashes. (Don't recommend) I am hesitant to say that the RESET switch has a short in it, but it's pointing to that at the moment. I am headed out of town for a week and plan on leaving it on the whole time to see if I come home to a black screen. I will update the post at the end of the week. Appreciate everyone's incite on trouble shooting this extremely frustrating situation. GGs boys and girls!

TLDR: RESET Switch cable to Motherboard has possible short, throwing CPU LED on MSI B550 and Q15 code on ASUS HERO VIII.
