Crysis warhead/wars crashing, driver related?

[wmdwmd123]

Hey when I play crysis warhead/wars it crashes sometimes. I got the crysis.exe has stopped working error 3 times and another message one other time, and it only happens in those two games. I updated my 4870 1gb to 8.12 drivers but it happened on 8.11 too. Does anybody have a suggestion?

please post complete computer specs... it not be just a graphic card problem... Might be an issue sometimes of under rated Power supply
