I just did a fresh re-install of windows vista on my computer and reinstalled the usual programs I use. Now, every 30 seconds or so, even if all programs are closed and computer is not doing anything, the hourglass symbol pops up next to the mouse and stays there for a few seconds. It's getting pretty annoying as I don't know why this happens. I ran anti-virus and anti spyware, and also removed some programs, but it still happens. The vista install is about 2 days old.

My specs if it matters:
core2duo 2.66ghz
3gd ram
evga 680i board
320gm HDD
8800 GTS 512mb video card

Hope someone can help!
