Random Freezing

[gigadager]

I didn't know where to put this so I decided to put this here.

My computer's been suffering from a lot of random freezes. I could go on for a few hours without an event, and on others, the freezes would occur back to back. I could do nothing except for a hard restart during these crashes, and it's to the point where I've had to computer just lock up on me on the BIOS menu.

Does anybody have an idea as to what hardware problem I'm suffering? Is there any program that could identify the problem I'm having or something of the sort?

Thanks in advance.

What components are installed? Do you have a quality PSU (a likely candidate for that issue)? Unfortunately no program can identify why the PC locks up.

I'm using a 650 W PSU, by the way, and I'm also using the stock thermal paste.

The stock thermal paste isn't the issue. What 650W PSU do you have?
