Dirt 2 restarts computer no bsod

[Venality]

I'm trying to play Dirt 2. but every so often My computer just randomly restarts..
this didn't start happening until after I got my new monitor. 21.5" 1080p
if anything I'm thinking it might be the bigger monitor pulling too much power off the PSU now with the larger resolution... but not sure, gonna retry my last monitor to find out.


600W PSU
AMD Phenom II X3 720
MSI NF750-G55 Mobo
4GB DDR3 1333 Gskill Ram
GTX 275
500GB Seagate

With a lower resolution, it doesnt shut off. it also shuts off when I have 2 monitors pluged in Dx

im having a similar problem! ummm so am i supposed to turn the resolution of the monitor down or the resolution of the game down? I have both at max... >.< and this only happens with this game! i play modern warfare, NBA 2k9, all need for speed, grid (same producer as dirt 2), etc... and only dirt 2 is giving me this problem! >.<
