When I play Oblivion, usually after about 2-3 minutes my computer will freeze. This also happens when I play Guild Wars. Sometimes though, I can play for longer (like an hour) without my computer freezing. I'm pretty sure I have a decent setup:
AMD Athlon 2400+ about 2gHz
NVIDIA GeForce 6600 GT 128mb
Advance AC97 Audio (onboard)
768MB RAM
I have updated Direct X. I run the game at the 640 resolution and have adjusted in game video settings to low.
Could the problem be that I'm running out of system memory while playing Oblivion or Guildwars?
Thanks for any help
