I lost a mother board a couple of day ago. I replaced it with what is supposed to be comperable to what I was replacing. I also had to reload xp and went from xp home to xp pro. I play half life 2 and the game ran fine before the switch. Now it runs so slow that it is unusable. Everything else seams to run fine. The pc has a celeron 1.80 processer with 576 mb ram. The new mother board I installed is a p4vm800 prescott 800 mhz. Can anyone give me some advise
