I've been having some problems with my PC lately. Sometimes when I try to boot, the fans spin up but it goes no further than that. Sometimes I have to power down and try multiple times before it boots. And I had one blue screen, and one instance where the PC just randomly powered down while I was using it. I was thinking that it could be either the mobo or the PSU (could be something else too I suppose. RAM maybe?). Is there any way to know without swapping out components? I'd rather not have to go swapping out the mobo because I'll need to get a new mobo, CPU, and RAM. Any advice is appreciated, thanks!
