Vista Computer freezes sometimes for a couple seconds

[wildgene789]

Alright I just built a beast computer in my eyes and it freezes a little.

**Problem**
at times when im just using basic computer usage like firefox, aim and searchin through my computer stuff it freezes for a few seconds then resumes. Now i think it might be that my hard drive is to slow.

**Specs**
AMD Phenom II x4 940 BE OC @ 3.6GHz
Asus M3N-HT Deluxe Mobo
4 GB Ram at 800mhz
250 gb hd 7200rpm
gtx285
600 watt PSU

Please let me know what you think because im thinking its because of AMD since this is my first amd cpu.

I had the same problem with Windows 7. The only fix for me was to re-install the OS.
