For some odd reason my cursor circles, as if busy, and freezes Windows for a few minutes. I just purchased this computer in May of last year and it's had the problem ever since. At first I thought it was internet related, but today it was the straw that broke the camel's back when it froze for a few minutes upon loading up the calculator.
I keep my computer very clean, I scan malware, adware, etc. religiously; it's not infected with anything whatsoever. I've searched high and low for any solutions to the problem and I was lead to these forums by this thread: Freezing busy cursor
They have the exact same problem I have, though I don't have the computer actually freeze to the point of manually rebooting it. It simply freezes for a few minutes then I can continue using Windows. Alas, I don't see any solutions in their thread. Was hoping there'd be better luck with mine.
