Random Freezing While Playing Games

[idata]

I have recently bought a dg41rq motherboard and running vista 32bit version(home premium) on it along with core2duo 2.93 ghz and 2gb ram.

Whenever i play some graphic intensive games like nfs-mw or burnout paradise my system works fine for some time but after some 10 mins or so it freezes and sound loops for a few seconds and monitor blanks (blinking monitor led), restarts itself. sometimes vista shows that it has recovered from a serious error " VIDEO HARDWARE ERROR"

I have updated all the latest drivers. please help me!!!!!!!!!!!!!

I uninstalled the latest intel g41rq graphics driver of intel from the programs and features and let windows install it's own driver( though experiencing a lag in performance). everything works fine now. maybe the intels latest driver is faulty.
