PC shutting down when under stress
PC shutting down when under stress
I've faced some issues with my PC over the past few months, but things have become increasingly problematic lately.
My system is an AMD Ryzen 5 5600X with an RTX 3080 10GB graphics card and a MSI PRO-VDH B550M motherboard, powered by a 750W gold PSU (brand uncertain). It runs Windows 10.
For years it performed well until recently. I’d be playing a game when suddenly the PC would shut down abruptly, with the fans running very loudly. Based on my research, this likely stemmed from a power surge affecting the GPU. When I played Railroad Empire 2, after unlocking new engines in 3D view, the issue would occur. I resolved it by reducing graphics settings; temperatures remained normal. The problem also appeared with other games. Graphics cards were up to date, though the issue predated my latest driver update.
More recently, during normal gameplay, the PC would shut down after just a few minutes of use—something that now happens consistently. This time there were no fan noises. I also experienced a blue screen upon first powering it on today, which is unusual. Examining event logs showed only a critical error during a hard reboot, with no other errors detected, suggesting a hardware concern.
I completed a FurMark GPU stress test and found it stable at 100 FPS in ultrawide 1440p, with temperatures remaining within acceptable limits after about 15 minutes.
The OCCT power test repeatedly reported an error every 3 seconds: “Error - 3D Adaptive - 785808 error(s) found ( GPU #0 - NVIDIA GeForce RTX 3080 )”. Repeating the test didn’t produce any errors, and the 12V rail stayed stable between 11.96V and 12.14V.
It performed adequately during the OCCT CPU and RAM tests as well.

Remove the side panels of your case and check the sticker on the PSU. You can also send a photo if you're not sure what to look for. Is the PSU three years old?

Functioned well for many years until recently.
Owners of an RTX3080 were recommended to use a 1KW unit because of high transient load spikes;

Hi maybe a more powerful PSU could fix your problems. Based on my experience with high-performance GPUs, it’s wise to choose a PSU with over 1000 watts for stable power supply and extra capacity for future upgrades. Power surges happen during intense gaming and heavy productivity tasks. I set my gaming PC to auto overclock as needed without crashes or errors. Just maintain your OS regularly and keep your games updated. I’m sure this will help you get your PC running smoothly again. Cheers.
