PC screens black/green screens and reboots

[Pejapw11]

Hello. I have a problem with my PC. I have 2 monitors, one (main) goes black, the side one goes green (dunno if it matters but yeah) and then reboots It does it very randomly. The crash isn't frequent, it's maybe like one or two times per 24h of usage

Changed PSU - didn't fix the problem. Nothing in my PC is overclocked at this moment and problem still persists. I can do any OCCT test fully without errors (1h) and it do not seem to cause a crash.

My full specs are :

B550 Mortar

Ryzen 7 3800x

32GB DDR4 3200CL CL14 Trident Ram

BeQuiet! Straight Power 11 750W Gold

XFX SWFT210 Radeon 6600XT

Does anyone actually have an idea what could it be or had similar problem and fixed it somehow? It seems to me like a GPU problem (?), maybe I did some damage to PCIE port on motherboad??

sounds like a gpu issue. could be dying. you could try using the HDMI and Displayport on your motherboard to see if the problem persists.
