Display driver stopped responding

I started playing about 2 weeks ago, and every time i play for some amount of time, the game freezes, then my screen suddenly gets larger, everthing goes off colour, and an the error "Display driver stopped responding" pops up. Too bad i cant paste a picture of it, otherwise you could read it, but ill just type it down
"The ialmrnt5 display driver has stopped working properly. Save your work and reboot your system to restore full display fuctionality. The next time you reboot your machine a dialog will be displayed, giving you a chance to upload data about the failure to Microsoft."
I just hope that im not the only one with this problem.
o ya, if u need this, ill post my computer info:
Toshiba
Genuine Intel(R) CPU
T2050 @ 1.60GHz
1.60 GHz, 1.99 GB or RAM
Hope this will help discover the problem! Happy gaming and figuring out the ClockWorks!
If you go through the Technical Help Sticky you will see instructions on how to find out what your display adapter (video card). You should then use this information to go to the manufacturer's site and grab a download of some updated drivers.
