Since about a month ago, my computer locks up whenever I play 3D games using my GeForce3 Ti 500. In RCTW, it plays for about 10 minutes, and then gives me a loud, long beep sound, and locks up. In Max Payne and 3DMark2001 SE, it locks up after about 15 seconds of gameplay. I'm using a ECS K7S5A Mobo, and this is a brand new card (I got it through RMA with PNY, and it used to work, but now it doesn't, so I believe the card is functional).

I'm also running WinXP Home, therefore running also DirectX8, and using Nvidias 23.32 video drivers. I also have a SoundBlasterLive 5.1 XGamer, and a standard Ethernet Card (I think 3Com), and a FireWire card.

Anyone have any ideas?
