3d causes crashes

[blueblob11]

Hey, I'm using linux mint 5, which technically isn't Ubuntu but it's based off of Ubuntu 8.0.4. I am using an alienware aurora m9700, which has nvidia graphics cards, and that's where I think my problem comes in. Any time I run a game\program with 3d graphics my computer overheats, I can watch the temp rise in the terminal with lm-sensors, and my comp just turns off in around 5 minutes or so of anything, including 3d (glest, brutalchess so far). Does anyone have any suggestions of what I should do?

Thanks

Have you installed Proprietary Graphics Driver?
Execute this

sudo lspci | grep -i vga
grep -i driver /etc/X11/xorg.conf

Post output here.

I updated to Ubuntu Jaunty 9.0.4, so I no longer need help for this thread, I'll start a new one for Jaunty.
