Company of Heroes crashing to desktop without reason. Why?

Hey guys.

I've bought this new comp and Company of Heroes with it.

Now, my problem is, the game crashes, and I don't know why.

My drivers are fully updated to the latest ones. I've tried playing it on Dx 9 (got the Dx10 ver) and therefore have tried to lower the graphics. Same **** happens, about 10-15 min into game.

Suddenly the picture starts to lag, BUT NOT THE GAME. The game flows as good as always but everything is kinda choppy. Happens in about 5 sec.

THEN, it freezes, and crashes to the desktop, saying that my monitordrivers have stopped to work andare now "rebooting themselves".

I try again, and same **** happens. Why guys?

Comp Spec:

XFX Geforce 8800 GTX - latest drivers.

E6850 C2D - shouldn't have problem with the game

2 gb RAM

It doesn't make any sense? :(

wrong board.

but could be the result of excessive overclocking of the cpu, ram or gpu.

I haven't overclocked anything, everything original and the computer is barely a week old.

AND I don't consider this as wrong board, since the COH board is kinda dead and this is a hardware forum.
