Hi everyone today I'm having a problem with a msi z270 a pro that gives me a post error (VGA) but it boots just fine in to windows. That's not all when I'm in windows playing(for example r6) the pc shuts down entirely(and by shutdown I mean powers off completely). What seems to be the problem? I haven't tried anything yet. It started doing this after a thermal paste swap on the cpu. And I just cleaned the gpus fan nothing more, the case was full of dust. (Tommorow I'm gonna try a different gpu, no gpu at all, and cleaning the connectors). The gpu is a Gtx 960(for now) and the cpu is a 7700k. Thanks for your help.
I bought a new PSU and it works. I had the exact same problem and as far as I know, this fixed it for me.
I would suggest just getting anything over what you currently have.
