This is a stupid question but have you checked Logitech's forums for anyone with similar problems? Have you tried other usb devices to see if they freeze up the system as well? If you installed the Logitech drivers have you tried just using Windows drivers for the mouse as well? I've never experianced any lock up problems except on a past machine with a logitech keyboard. The logitech keyboard software was causing shut down issues but was fixed with an update.

P5ND2 SLI Deluxe

just wondering if any one can help.

Got a water cooled system decided to upgrade my graphics to gigabyte 6600gt 256de passive cooled, stripped the cards down put them in the system with the waterblocks on, fired up and changed the drivers....no problem, trouble is when ever i try to get 3d rendering out of the cards they send my pc in to blue sceen mode, cant play games cant run 3d mark. Trouble is the cards work in every way on my asrock test board. if anybody needs model numbers let me know.

Thanks in advance.

I experience the same problem my system was running stable with norton until I used sata raid0. Took me 5 days to figure it was norton nis and your post confirms it thanks. Now I can transfer 11gigs of stuff on the raid 0 without freezing.
