THank you but I think I may have found the root of the problem. I think it was Norton Internet Securty 2010. I have been running windows for a couple of hours without it, and the incident hasn't happened yet.
But now I am stuck with no internet security, can anyone reccomend a good native x64bit security software
you have an i7 and it does that to you.. I've got an i3 and NEVER had a problem . . I think free anti-virus is best :P AVG
I one that works well as a firewall, and doesn't hog memory
