My PC was working fine a day ago, I had it at my girlfriends house and it was perfect then I brought it home hooked it up and no I get a stuttering of the mouse and music and such every now and then. I tried re installing windows in and that was no help I am not sure what is causing it I have anti virus running and spybot and still no go. I recently got a 160GB WD SE hard drive but everything was working great after install so I dont think that is it. I have a GA 7DX MOBO with lastest bios. 768 MB of PC 2100 ram. The hard drive a GEforce 3 and a TDK Burner and Creative DVDrom. Any suggestions are greatly appericated. Also running XP Pro and Office XP w/frontpage.
