Hi, I recently upgraded my motherboard, memory, and OS for my main PC. Here are my rough specs...

Specs:
Intel Q6600 G0
Gigabyte GA-EP45-UD3R
8GB GSkill DDR2 1066 (4X2GB)
Gigabyte GeForce 8600 GT
Windows Vista Business 64-bit

Overclock Settings:
3.2 Ghz Stable (400X8)
CPU vCore 1.25V
System Memory Multiplier 2.66 (1066)

About every 20 minutes or so, the computer freezes for about 2 seconds, then goes back to normal. All of my drivers are up-to-date. Malware and anti-virus scans are clean. Memory tests good. Is this a voltage problem. What could this be?

Thanks

What are your HDD's?

SSD's?

Both are Seagate Barracuda's. OS drive is is a 250GB and data/scratch is a 500GB.

P.S. I blue-screened for the first time today...three days after I was Prime95 stable for 12 hours.

Do the following:

1) Set all clock settings to default, non-overclocked settings, and
2) Remove 4GB of RAM.

Memory tests are NOT 100%. However, if you remove 4GB and things are fine it does not necessarily mean the RAM was bad either. It could also be the motherboard or power supply.

Make sure you put the two sticks in the right spot (see your motherboard manual).

I'm willing to bet if you two the two things I mentioned your system will be stable. If so, then simply make one change at a time until you are happy or find the fault.

As mentioned by photon boy put all your settings to stock and if it works properly you know it's an unstable overclock. Also Prime 95 stable doesn't mean your system is always, no matter what, totally stable. On my previous overclock settings my PC did 13 hours of prime 95 no problem but crashed playing COD:World at War after 15 minutes.
