Question PC randomly black screens while gaming ?

[ArmoredRhino187]

Hi all

The issue I am having is whenever I am plaing games on my pc sometimes the system will crash, the screens will go black and the pc will just boot back to the windows login screen

I have monitored my temperatures to check the health of my components and they seem to be fine GPU on load is around 55-60 celcius and cpu max out at around the same. Ive checked and made sure its not my drives either as moving the OS and games to other faster drives proved no use. Also did a calculation of my PSU load and I would be averaging out around 485 under load. Would there be any other reason why my system would randomly black screen on me?

Many Thanks

First thing that get's a comment here is that low quality psu, can you test with another one? Maybe from a friend or you have a local pc shop ....
