Built myself a new system!

What is the source of the freezing do you think?

The motherboard seems to be very temperamental in regards to memory you equip it with, and my processor was only supported after flashing the BIOS to a recent version.

I've been troubleshooting it for a few days, and I may have gotten it fixed this morning. I got it running a stress test at home while I'm at work to see if it's resolved, as it never really run for more than an hour doing anything more than surfing the 'net, so having it under load for a few hours should tell me for sure.
