I have an i5 cpu 4GHz DDR3 with MSI HD5850 and I get crashes over and over again playing both Crysis and Crysis Warhead on Windows 7 ultimate. I have updated the video driver more than once but it does not help. Does anyone know why? Robert

I second that your overclocked coudl be the problem here.
Try msi afterburner and give her a little more juice
Does your system crash when you run GPU benchmarks?
