I have a FX5900 nvidia video card. Recently the video started "freezing" every 2 to 3 seconds, which is really disruptive to all of my gaming. The only thing that is different is that I have installed an anti-spyware program and have operated it once. The program found 3 "spyware" applications and stated that removing them might cause "interuptions" of some of my other programs. I did not expect intermittant display "freezing". What can I do about this very annoying situation?
