tech support Random black screen locking up my PC

[TheOfficialUno]

Hello,

For the past two months I have been having an issue with my at the time 4 month old PC. Randomly, both displays will go black while the computer stays active. Only a force restart does anything and usually after force restarting, nothing will happen orher than the lights turning on.

 

What I've/ my friend have done:

Turned off and on again,

Unplugged and replugged everything,

RMA'd the GPU (Zotac held on to it for a month and did not say what they did or how they tested the card,)

Bought and replaced the motherboard,

Swapped the RAM positions,

Taken the entire computer apart and put it back together,

Switched from Windows 10 to Windows 11

 

I am past the refund period and spent too much on it to let it collect dust. Any help on what to test or replace would be appreciated.

 

Relevant Specs:

AMD Ryzen 9 7900x 16 Core

Aorus X670 Elite AX

Corsair Vengeance (2X32) 64GB DDR5-5200 CL40

ZOTAC GAMING Trinity OC RTX 3090 24GB

Corsair RX850W 80+ Gold PSU

Windows 10/11

Additional information:

BIOS version was the newest for the motherboard listed above.

 

Programs that have caused crashes include: Steam VR, Blender, Stardew valley, Vortex mod manager, Gigabyte's motherboard software, Firefox, Windows itself, and Nvidia Driver installer.

 

All drivers were up to date at several points in these past months and the issue had continued from install to install.

Hey,

 

have you managed to resolve your problem? I have very similar problems with my build. Random shut downs, even under low load. Instead of the RTX 3090 I have a 4090 but the problems remain the same…

Black screen and it doesn't recover or shut down? Well it's not the GPU, it's likely anything between RAM and CPU. RAM doesn't seem too high speed or anything, and CPU isn't overclocked I assume? Anyways, I'd replace the platform, RAM+Mobo+CPU with spare parts if possible to narrow it down. RAM usually freezes the computer and sometimes does weird things to sound and picture, Mobo can do randomly anything, and CPU usually BSOD or restarts the computer abruptly. AM5 is a new and imho an untrusted platform that even LTT made a video on why they didn't have a review video on time.

Any clues in event viewer? Or does the PC not last long enough to get there?

Sad to see this thread has little replies, I am having the same issue. 

 

Playing games, nothing intensive, then randomly about twice a day my computer crashes. Brand new build. Screens lose signal, mice and keyboard still have power, CPU fan running, CPU error light on the motherboard is on, the front io power button will not shut off the machine only a flip of the PSU will. After restarting everything is fine for extended periods of time. I have seen others post similar issues stating the motherboard is faulty but those can't make it to Windows, mine will run beautifully till it shuts off. 

 

This is a brand new build as of late May, I was out of town for a while and only got to try it out for the past few days when I discovered this issue. I really hope I don't have to send back any parts and if I do I hope they have some kind of warranty.

I disabled xmp after the first occurrence since many say ddr5-6000 does not xmp well but the issue persists. 

The lack of a blue screen makes me want to rule out software or heat issues, but I am by no means skilled in computers post-2013.
