BSOD while playing games

Archived from groups: microsoft.public.windowsxp.games (More info?)

I am frequently experiencing a Blue Screen Of Death while playing games. A
blue screen comes up, with no message on it and I must restart my computer in
order to use it again. The games this occurs in are The Sims 2, Brothers in
Arms, Swat 4, Day of Defeat, Half Life 2 and FarCry. It's really, really
grating my nerves because I have tried everything! Please help! Thanks. This
is what the event logs give me:
