Ok I am at a complete lost, my moms PC just started Freezing/lagging really bad. It only happens when you try and use stuff like youtube, Java games, any game, Limewire anything.. When you have Winamp turned on It starts skipping the music, but will continue to play. but you cant do nothing for at least 2 to 3 minutes. Than it will run fine for about 5 to 10.. All I know is she has a P4 1.5 512MB ram, 40gb HD, 16Mb nvidia vanta. I have done all the normal Trogan/Virus scans and it shows up all clear.. Any Ideas on whats going on ?
