Hi there,
I have the same problem. Did a fresh install of Ultimate x64, the first
days installing went smooth, then suddenly the mouse pointer freezes for
about 5 to 10 seconds.
It started after soms updates from windows I think...
I did some googling around, found lots of info (lots of Dell pc's), non
of the trick did it for me..

.
But i don't have a dell so they aren't the problem.
My system is as followed:
Asus A8N-SLI Premium MoBo.
AmD x64 3800+
3Gb Ram (2*512Mb + 2*1Gb)
Geforce 7800GT 256mb
System is installed on a RAID1
I really hope to find a sollution... :shock:
