PC Freezes randomly

Hi all!

I have a question that I'm hoping to get answered. I have a problem with a recently built PC that freezes. No matter what I'm doing, from only running Firefox or playing video, or playing a game. When happens when it freezes it will freeze for a few seconds and unfreeze, then resume freezing. While just listening to music the system will sometimes freeze for 1 - 2 minutes at a time, whereas while playing a game it will freeze a couple times and then continue on as normal. I have installed the most recent video card drivers. I have also replaced the ram with different ram. (Originally thought that was the problem despite it passing memtests in earlier tests) I've also stress tested the system for approximately 10 hours with no issue. Max temp I believe was low to mid 70's but I'm not 100% certain.

Specs:
MOBO: Asus p7p55d (Deluxe)
CPU: Core i5 760 (Lynnfield)
RAM: Ripjaws 4gb
Video card: ATI Radeon HD 5770
HD: 1.5TB WD Caviar green
Windows 7 64bit

Any help is very muchly appreciated! :D

Model and manufacturer of PSU?
Random freezes are one of the most difficult problems to diagnose. If the stress testing was done with prime95 then it is possibly software issue.

Haha you're telling me it's difficult to diagnose. Oh well. PSU is an OCZ Modxstream Pro 700w. And yes it was done with Prime95. I have also attempted a reinstall of windows but to no avail.

Motherboard drivers good? Newest drivers for the GPU could be an issue rolling back to older version might be better (been awhile since HD5770 was released) since the newest drivers are optimized for the newer cards.

Ah ha! I knew I forgot to do something. I'll have to try updating the mobo drivers. Thanks rolli59, I'll let you know how it goes.
