Monitor turning off when loading games...

[Dyson]

Hope someone can help me out here. Recently built new pc, and everything is great, EXCEPT that when I start certain games the monitor "pops", and turns itself off. I have to then unplug it from g/card, and the mains, then plug it back in and its fine.

Works fine on all HL2 games/mods, and Trackmania United. Doesn't like BF2, TestDrive Unlimited, Prey, or 3d Mark. Happens on a reset too.

Specs:

E6600 @ 2.7
4gb Geil ddr2 @ 800
OC2 8800 gts 640mb
EVGA 680i mobo
Vista 64
Viewsonic VA2012w


Hope someone has an idea!

Could be something to do with the resolution, happened a lot with my old CRT when it didn't like high settings.
