No clue as to why this happens. But when im playing any source game, i average around 30-60 fps. At random points while playing the game will lock up, causing the frame to freeze and the sound to repeat itself over and over. This happens with no other games like F.E.A.R, Joint Ops, Or any other game. SO far, its happened in DoD:S and CS:S. I have updated drivers (not betas) and i have no spyware i believe. (usually it olny get up to about 22-24 processes. I start the computer with 17.) Ive cleaned out dust from the fans and heatsink, and have a good power supply. Anyone got ANY IDEA AT ALL!!! to why this happens please help!! my specs are: Windows XP SP2 1 GB RAM AMD Athlon 2600 getting 1.91 Ghz Geforce 6200 128 Vid RAM EDIT: one interesting tidbit: the lockups rarely happen on the map CS_office.
