System question about restart?
System question about restart?
I have observed an unusual occurrence now. I mentioned that my GPU silicon isn't very effective for VRAM tuning, which frequently leads to crashes. However, I recently tried overclocking the VRAM beyond what I normally do and it didn't crash. So I reverted to the default settings and continued with my usual underpowered configuration, about ten minutes later the PC restarted again. I believe adjusting the VRAM settings causes a reboot, regardless of whether I actually use those settings or not. If I change the VRAM tuning and the system doesn't immediately crash or restart, it will happen no matter what.
I'm using the ASRock b650 pro rs, but can't locate this setting. Also, I'll consider upgrading to a bigger PSU just in case—it's quite costly. Is there any way to confirm if the issue isn't related to the GPU, CPU, or board? I don't want to waste money on a new PSU if it doesn't solve the problem. Recently, my PC restarted immediately after exiting RDR2 and almost as soon as the wallpaper engine started. This time, I hadn't overclocked the VRAM at all (at least during this session).
To verify the problem, temporary replacements would be necessary so each component could be isolated and potential causes identified one by one. The PC’s ability to handle stress tests suggests the motherboard, CPU, and RAM are likely fine. I share your view that the PSU might be the issue based on the information given, though it’s not certain. Running the system with a higher capacity unit (like 850W+) could provide more clarity. Testing with a less demanding GPU might also help determine if the problem lies with the PSU. If the system experiences BSODs only when idle and under light load, this could indicate a PSU failure. We cannot confirm it with absolute certainty without direct access to both the PC and the PSU.
it's not a major problem—the hotspot is located on the GPU die, and the GPU temperature is being monitored on the PCB. you might be able to reapply high-viscosity paste to prevent sliding, though the GPU could slow down slightly; it won't restart immediately.
Thank you for your response.
I also attempted significant undervolting of the GPU and stress testing; however, the system didn't restart but instead crashed briefly before returning to normal operation.
It seems the most frequent crashes happen when shutting down Red Dead Redemption and switching to desktop mode, as the wallpaper engine triggers a reboot immediately.
If anyone has any tests or approaches to more accurately identify and resolve the issue, I would really appreciate it.
One was for testing the PSU is using the kind of testing equipment found in electronic laboratories, the kind that people who review PSUs use, which are not avilable to home users like us. So this one is out of question.
Only sure way is to test the system (and run the games you run and try to replicate the situations) with a good quality at least 850W PSU which is known to be able to handle spikes from your graphics card.
As I said before you can also try and check other components. As I said to make sure you each one of them work properly you have to apply a process of elimination.
Again, since the system can go through stress tests without problems (13 hours of Prime95?) the MOBO+CPU+RAM combo is working OK. There's no overheating either, otherwise you'd notice or it would show during stress tests.
Ultimately, the choice is yours. It's perfectly fine to explore alternative solutions and gather more details about the problem.
I performed a small test to verify everything and am now even more confused.
I used my custom preset with the GPU underclocked and undervolted, played for about 2 or 3 hours, then turned it off. About 5 seconds after the wallpaper engine started, the system went black with a buzzing sound before rebooting.
When I repeated the process with default settings (stock GPU), the game warmed up, I turned it off, and it didn’t crash this time.
I plan to recreate the issue again with different configurations, but I really disliked the black screen and buzzing audio situation, thinking it was mostly a VRAM problem.
