Pc crash while gaming

[haneksolanek]

Hi,
I am ocasionally having a pc crash. It happens always while I am playing games. The issue looks like this: The screen goes to a random color( dark green, black, gray), but the sound continues. I have to reboot the system, ctrl+alt+delete doesn't work. I tried reinstalling gpu and audio drivers, but it did not help. This issue happens just around once a week but I am worried. Can anyone tell me whats wrong ?

Whenever your PC crashes while gaming, it's better to check your CPU and GPU temperatures.

My temperatures should be ok my CPU have around 50 degrees while gaming and Gpu about 70. I never had this issue before and the temperatures are the same.

What is your PSU? This is either an overheating problem (which you don't clearly have), or a Power shortage.

I have a Corsair VS650 650W, I know that it isn't top notch, but From what I read, it should be enough

Are all cables connected to the motherboard/GPU firmly attached? Is the 6+2 connector firmly attached? Does your PSU pass the clip test successfully?

Yes, I think so, I did move all my components to a new case about a week ago, so I needed to reconect all the cables. The isssue did happen in the old case too so this issue shouldn't be connected to the case switching. The only thing I did change was Ram, because my old ram died.
