Question PC display goes off randomly

[kreiger1234]

Hi
I've been facing this weird issue for weeks now where randomly my PC display goes off. It starts generally when I am gaming but then after restart the frequency keeps increasing to the point the display just stops coming out of GPU. The iGPU works fine.

I thought the gpu was dying so i bought a new one and then the issue came on the new GPU too.

Old GPU 1660 Ti, New GPU ARC B580.
PSU - Corsair CX 650-F RGB.
CPU - i5 12400
RAM - 32 GB DDR4 3400MHz

I have been trying and trying but i haven't been able to reproduce it effectively, it is just random.

On the new gpu, i ran kombuster for 26 mins, absoluty no issue seen. And then as soon as I launched a game, display went off within a minute.
When the new GPU also started to not give any display, it scared the heck out of me thinking PSU burned it for something, but after keeping the system off for some time while GPU was removed and reinserting it brought display back again at which point i again shut off and removed gpu to prevent any further issues, going to test new gpu on a friend's system tomorrow hoping i did not destroy a brand new one.

Right now, i have my old gpu in the system and it's running fine for almost 4 hours now with continuous occt tests, kombuster, prime95 etc alternatively to allow for voltage spikes etc in order to test the PSU. No crash or display loss at all.

I just don't understand what's going wrong since i just am not able to reproduce it effectively.
Any suggestions I wholeheartedly welcome because I am just tired with this issue.

Event viewer doesn't have any entry at all when display goes off, no dump gets created as well, I just don't find anything to work with 🙁

If the issue happens again, I am going to try attaching the HDMI cable to the iGPU port on motherboard and see if the display is jumping to that.

Forgot to mention, before I bought my new GPU, i tried with another spare PSU i had with my old gpu, and i got a similar display loss there too once. Which is kind of why I believed tbe issue was with the GPU.

Welcome to the forums, newcomer!

A system abruptly shutting down when taxed can happen for one of two reasons;
1| you're having an overheating issue
or
2| your PSU is incapable of powering your system when taxed

Old GPU 1660 Ti, New GPU ARC B580.
PSU - Corsair CX 650-F RGB.
CPU - i5 12400
RAM - 32 GB DDR4 3400MHz
Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

i tried with another spare PSU
What would the make, model and age of this spare PSU be?

Hi Lutfij,

CPU: Intel core i5 12400
CPU cooler: Corsair H100i V2
Motherboard: MSI PRO Z690-A
Ram: 32GB DDR4 3400MHz Kingston Fury Beast
SSD/HDD: 2x Nvme 1TB Crucial P3, 1x WD Green 128GB SSD, 3x HDD (2TB+1TB+500GB Seagate Barracuda)
GPU: Zotac 1660 Ti (Old), Intel Arc B580
PSU: Corsair CX 650F RGB (in the build), Corsair CX600 (spare)
Chassis: Phanteks Enthoo PRO ATX Full tower
OS: Windows 11 21H2
Monitor: 2x HP 1080p, 1x LG 1080p (Multi monitor setup)

The PC isn't shutting down, it's going into a display loss. I have to hard reset it in order to bring it back.
Overheating would make sense, but then again i've stressed it for 4 hours after last failure, hasn't crashed yet, with same components.

And if PSU was the issue, then again i expect the behaviour to be reproducible under load. It's essentially just behaving randomly.
Ans i wouldn't expect same behavior with the spare psu too.

I am inkling towards it being motherboard but essentially just not able to pinpoint it.
