BSOD with new CPU

[reignsupreme11]

hey I wasn't sure exactly where to post this, but i figured to go here and in the CPU section. I recently purchased a new cpu and cpu heatsink, and that time about 3 weeks ago i've been getting steadily more frequent blue screens of death. They pop up far too quickly for me to read them and my computer does an automatic reboot. they happen at the most random times--from while i'm browsing, listening to music and messaging, to playing demanding games like dawn of war 2 or fallout 3. the cpu was a budget upgrade and could be the problem but i can't tell. It's really frustrating and I'm up to having about 1 BSOD each day. any ideas? This has happened with an OC to 3.1GHz @ 1.45 volts, 3.0GHz @ 1.4V and now again at 2.8 GHz and 1.35 volts, so it doesn't seem to be an overclock issue. Virus related? i have norton 2009....any ideas?

My system is:

Gigabyte GA-MA78GM-US2H MOBO
QuadCore AMD Athlon X4 620, 2860 MHz (13 x 220) with OCZ Gladiator Heatsink
2 x 2GB Corsair XMS2 CM2X2048 PC6400 @ 880MHz
Disk Drive Hitachi HDP725050GLA360 (500 GB, 7200 RPM, SATA-II)
Video Adapter NVIDIA GeForce 9600 GT (512 MB)
OCZ 600W ModXStream Modular PSU
Windows XP Home Edition SP3
