I love to play my Company of Heroes. However, in the middle of the game, either the game crashes to the desktop with the message "COH has to shut down" or gives me the blue screen which subsequently shuts down the computer. This is the same for any newer games which requires powerful performance, ex.World in Conflict. The problem didn't exist in the beginning but now it is more frequent than ever. So I formatted the computer and installed the Windows Vista 32bit Home Basic while I was at it. But problem persists. When the blue screen pops up the screen displays something about "IRQ is blah blah, dumping physical memory." Here are my specs: AMD Athlon(tm) 64 X2 Dual Core Processor 5000+ 2.60 GHz 2046 MB RAM NVIDIA GeForce 7950 GX2 SLI 150GB Hard disk Please help me, only games I can run are primitive. I have resorted to entertaining myself with minesweeper.

The exact message on blue screen is BAD_POOL_CALLER

u have 2 7950 GX2's running in SLI? on vista? that probably the problem right there. or u may have a lacking power supply for running two 7950 GX2s. they r power hungry beasts.
