Could someone look over my hijack this log please?

Also, I am having a problem running games. When I start a game, it allows me to go through the menus fine and everything, but once the actual gameplay starts, it freezes for a long time and will spastically return to being fine, but only for a second. I have been playing these games forever and have never had problems. I just reformatted my computer too, so I think it might be something physically wrong. Does anyone have any suggestions? Thanks for the help.

Thats a clean log. A thing I can suggest and I can say is mandatory, is getting to Windows Update and get upgraded to Windows XP Service Pack 2. Also check back after you've installed SP2 and install the rest of the Critical Updates. Post back on how it goes.

I installed SP2 and all of the updates needed. I reinstalled the games that were giving me problems, and it still has the same problem. Should I mention that the games giving me problems are EA games? (NBA Live 2005 and Call of Duty) If anyone has an inkling of what may be wrong, please please please help! Thank you
