So I have been having this issue with my desktop where if I try to run software for more than a few minutes it shuts off as if it was just unplugged.
software like; pearson, word etc
or even games like minecraft, warframe, or sims.
internet is ok.

I bought a new power supply and it's not over heating.

Wouldn't that produce an error message? I get the black and white windows did not shut down properly screen when I turn it back on but thats the only evidence that theres an issue. Although very recently It has started running slower..
