Hiya.

So, I've been having issues with my PC since a month or so, it just shuts down by itself and it (usually) keeps shutting down repeatedly if I try to reboot it afterwards. It's pretty much random, some days I get no shut downs even after 4 hours of continuous usage and then the next day it happens after just 15 mins.

I was thinking that the issue could probably be the PSU, but I don't want to change it blindly and then finding out that the problem was something else. Any ideas of what should I do?
