Solved My New Build is Freezing

Hello everyone. I am having issues with my computer freezing. It's not frequent but it and it happens pretty much whenever it wants. I can be rendering a video in Premiere Pro CS5.5 or just downloading something with the system completely idle. I check the Windows System Logs after every freeze and they're no help, they just say the last system shutdown was unexpected at the time of the reboot.

I ran Memtest86+ 4.2.0 and it came up with no errors. I also ran 3DMark Vantage, I know it's not really a stability test but I wanted to see if it would cause it to freeze, which it didn't. But then I ran Prime95 on a stress test and it causes the machine to freeze after the 640K Self-Test passes everytime I run it.

I have attached a picture of where the computer freezes everytime I run Prime95, as well dump and system file collection.

I even went as far as doing a fresh install of Windows 7 Ultimate to see if my install could be the issue, which it wasn't. Could it be a CPU issue? Overheating or a CPU issue itself? Or could it be a memory issue even though Memtest returned no errors? Or even a power supply issue? I have enough money to drop on a new PSU or cooler for the CPU but I really don't want to have to buy a new CPU.

I built this machine in May and it seemed to perfect after the initial setup. If you need any more info just ask. Any help will be greatly appreciated. Thanks a bunch.

I solved the issue, turns out it was somehow my Firewire card. I was going to try eliminating possible RAM issues, but I suspected it was the cheap Firewire card I installed. So I pulled it, ran Prime95 and it made it all the way through the 8k test. Unfortunatly I kind of need the card, I'm going to try to RMA it and buy a different one.
