Computerski ist Kaput

One of our two main computers has pissed me off for the final time. If you turn it off for more than ten minutes, it will not boot when you turn it back on. It powers up, and the fans and hard drives start spinning, but no boot. To get it to boot, it must be left on for an hour or two, and then be reset. I thought it might be a power supply issue, but it wasn't. Screw it, we're making a new one.

This is what I ordered. It seems like a pretty powerful combination, especially for under $1k. What do you think? Did I goof up somewhere?
