I'm at a total loss here, everything I've found doesn't seem to be the right fix. My PC will restart at least 2, sometimes 3 or 4 times a day, it acts like a power thing, but I don't think it's a power thing. I'm getting no error messages or anything, and I'm at a total loss. It seems to be specific times almost, but I haven't payed close enough attention to when the computer actually shuts down. So any thoughts on what it might be? It's a home built system, that's normally pretty good except for lately.
