Technical Xp Sp2 Explorer Problem, Or maybe hardware...???

Archived from groups: alt.comp.periphs.mainboard.asus (More info?)

I have a problem with a relative new PC I've built several month ago,
and from then, I have no peace of mind... I'm almost sure there are
helpful members that have the knowledge and good will for helping, so
here is the problem:
The macine is mostly used for video editing (Prem pro 1.5, Encore,
Ulead Media studio and so on), and Graphics as PS, + + +...
>From time to time the pc just "freezes" and I have to reboot. Sometimes
it "just" slows down , and again I have to reboot.
The windows task menager is always at CPU 99% and the process that
takes all the CPU's resources is EXPLORER !!!
I had the same problem with it whe SP1 was installed, exactly the same.
As I have the clean "ghost" I've made when I've installed Windows, I
don't suspect any spyware, virus or like them doing the problem. I've
tried to tweak the whole system without any improvement. Tried all Anti
virus - anti spyware - anti trojs...
I'm always got the same results....slowing and rebooting...and I don't
know what to do... I've moved the Paging file to another disk, made it
8G....no way...

I'll be very thankful for any help or idea

TIA

Nina
