Recently I built a new computer, before I go any further I'm going to list each item that is in my computer. I'll provide links to specs to make it easy for everyone.

The following items I took out of my old computer and put into this one until I have the money to replace them. My old PC worked perfectly fine, and as of now ran better then my new pc due to this problem. but I wanted to upgrade to a dual core.
NIC: Bigfoot Networks K1 (https://www.newegg.com/Product/Produc...82E16833342002
Graphics: BFG Tech BFGR79512GTXOCSINE GeForce 7900GTX 512MB 256-bit GDDR3 PCI Express x16 (https://www.newegg.com/Product/Produc...82E16814143062
Now with all that being said here is my problem. I'm going to use World of Warcraft as my example, though it happens with any game I play (half life 2, stranglehold, quake wars, bioshock, etc)
When I'm starting out I'm sitting at about 60 FPS. After about 7 minutes or so, the whole system will lock up on me for about 8 seconds, the sound will stutter. Going from 60 FPS to 4, then after the 8 seconds or so it jumps right back up to 60 FPS. There no consistency as to why it would do this. Once it does it the first time (since i started playing) it will happen over and over every 2 minutes or so. Sometimes it will lock up so bad I wont even be able to bring up the task manager. Other times I can bring up the task manager and just terminate the program.
I'm usually pretty good as fixing this stuff. But this one has me stumped. I have all the latest in driver/ windows updates. shutting my anti virus off doesn't do anything. I tried different NIC, disabling the sound. The only thing I can think of is heat. But in my opinion it fixes its self too fast to be a heat problem. Though I have been wrong before. If its not heat, then i would guess that it would be something related to the motherboard. Though I wouldn't know what, hence why I've turned to the help of others
Any help would be greatly appreciated.
