Windows 7 Ultimate x64 random freeze problem

Hi there!

I'm new here, but it seams there are some really good pro guys in here that might help me with this problem that's driving me insane...

A month ago I started experiencing random system freezes (system halts for ~30sec and then resumes to work normally).

I thought it was my Win7 going insane, so I did a clean install, but the problem is still present. I read somewhere that SP1 might be the cause, so I haven't done an update to SP1 this time - but the problem remains.

Could someone please help me with this?

If I need to post some screens or dumps, please inform me what needs to be done, and I will do it...

Thanks!

No one can help me on this? :/

drove me nuts for months, try uninstalling update KB971033, worked 4 me, so far so good
