Hi, I've been using this Vista computer for a while now, and it has had some problems but recently none. Now however, it freezes every couple of minutes until i hit control alt delete and cancel it. When the computer does freeze, I can select desktop icons, move my mouse around and look at what is happening, but I can't interact with any of the windows itself. If i try to move one, or select it, nothing happens. If anyone knows how to solve this it would be great. This is very annoying. Thanks
*Edit*
I am using dual monitors, so if i have a game running in windows mode on one monitor when it has "frozen" i can still play the game fine.
