Pc freezes with a random color while gaming

[tunda123]

Specs:
Ryzen 1600AF
Radeon RX 550 4GB
ASRock b450m steel legend
2x8 ddr4 2666 mhz
Gamemax GP650, 650W
1 M.2 ssd
Windows 10
BIOS 2.90.

After playing a bit, the computer becomes unresponsive and the screen turns into a color that is usually on the background with a sound like ‘RRRRRRRRRRRRRRRRR’.The problem usually happens while playing lol, but it already happened at csgo too, in valorant I didnt find any crashes. The only solution is to manually reboot.

I ran memtest and didnt find any errors. I also ran Furmark for more than 1 hour and the PC didnt crash. I tried 21.5.2 and 21.6.1 radeon software and in both drivers the problem persisted. What could it be? All components are new.

Those are classic signs of a weak PSU that is overheating and being that the PSU that you have is of poor quality I suggest that you get the PC tested by a local tech who will have an appropriate quality PSU or if you can see if you are able to borrow a good quality brand 500W PSU that is a minimum of Bronze efficiency rated, Corsair, EVGA or Seasonic are the type of quality that is needed.

Fwiw, your model of PSU is on Tier D • Recommended only for very cheap, iGPU systems here which means that it should not be used anywhere near an add on video card, you may have damaged your GPU by using it.
