Faulty PSU?

[Blanko]

So, i built a new pc at the start of the year and around 2 months after my build my pc started to crash to a black screen. This happens at random times so i cant pin point the issue. Sometimes it will not happen for a week or two or even a month and sometimes it will happen twice a week. I have reinstalled drivers and updated my bios ran memtest cleared the cmos and reinstalled windows and checked every cable and nothing works. This can not appear for awhile like 2 weeks from now or even a month so i am not sure how to proceed. The computers temps are fine around 30-38c idle on the graphics and around 40-45c on the cpu. I have tried everything i can think of and have no spare parts to try so was wondering if this could be a faulty psu?. I have asked so many people and i think there as confused as i am on this issue.

Ryzen 5 5600x

Corsair rmx850 PSU

Radeon 5600 XT Graphics

ASUS x570-E Gaming Motherboard

2x 8GB 3600Mhz Dominator Platinum

Samsung 980 Pro Nvme

Corsair H100i Elite Capellix AIO

it might be worth a shot to try a different PSU to rule it out.

If you are getting BSOD (Blue screens of death) maybe check to see if windows tells you what is wrong in crash dumps

(Theres people on here that can read them)

The pc will like reboot to a black screen causing me to hit the restart button to fix it. When i look in event viewer the only thing i see that stands out is Critical Kernel-Power  the pc has not shutdown properly event id 41 when im on a fresh windows install. Heres a dump file from windows 10 awhile ago which i managed to get after it happened.

What shows up in your Reliability History when this happens?

 

This can either be a crash, or a lock.  Crashes are easy to diagnose, while hard locks are much more difficult.

Only thing i notice befor it happens is my screen will freeze then i will be at a black screen and all the rgb is still on. Once it happened the rgb flickerd for about a second and one time it happened i could not boot back up i had to shutdown the pc for a minute or so.

Everything looks fine in all the logs and stuff other than the critical kernel-power message i mentioned. My system aint overclocked and its all on stock settings. I have reinstalled drivers, updated bios, reset cmos, reinstalled windows, checked every cable inside the pc, reinserted the ram and graphics card and also ran memtest. I aint sure what else to try. This all sound like a psu problem? because i was thinking about contacting corsair for a fix/replacement.

With no crash messages and the black screen lockup, it's more likely a GPU issue - I figure 55% chance of a GPU, 40% chance of PSU, 5% something else.  That being said, I'd try the PSU first because of how painful it is to get a new GPU right now, and how the PSU can kill other things if there are problems with it.

Ah thanks. I hope it aint the GPU because i only got it just over a year ago. I have the MSI Radeon 5600 XT Gaming X which pretty much went out of stock 2 weeks after i got it. I really hope its the PSU then and that i can get a replacement.
