Well I suppose it was running better. The keybored and mouse were going good but started to screw up again. its almost like when I try something you suggest it works great for a while and then all of a sudden comes back. and yes I have no antivirus on the computer now. Also I should mention that the same thing happens to the sound. Like it works fine then gradually gets worse. Also I cannot install SP1 it always encounters and error or even gets a bsod during install and reverts the changes
