Dying Compy

Well, my computer has been blue screening itself with a "MACHINE_CHECK_EXCEPTION" a lot recently. I get about an hour of use before it dies and i have to restart it.

I ran some diagnostics, and it doesn't appear to be the motherboard, CPU, or RAM. I had this problem before when i had my hard drives connected to the Nvidia raid controller on my board (an A8N-SLI premium), and after moving over to the silicon image raid controller, i thought my problems were solved. It was ok for about 6 months.

Well, since all the system hardware checked out, I'm beginning to wonder if the problem lies in one of my hard drives. I have two 10k raptors for an OS, and a 500GB drive for data, and one of them is ... squeaking. I think it's the 500GB. more experiments tonight...
