consistant crashing when playing games

[jimpyland]

hey people just joined this site and I'm happy to be apart of it.

I got a beastly computer which cost me a lot of money and the problem is it constantly crashes during games. it gives me a variety of error messages, all having something to do with "your rendering device has been lost" or the more common "your graphics card has crashed. please update drivers blah blah blah". the computer has been looked at by the company I got it from, Microsoft, Frys electronics and a friend and nobody can figure out what it is. the drivers themselves are fine, the card itself has allegedly been replaced several times.....im at a lost and this is my lively hood here. if anyone can provide assistance I would be extremely grateful

Please add your systems specs to your post with make and model#'s of the various parts. We need some idea of where the problem might be. Please don't forget the PSU, we need the make and model# of that as well since its the lifeblood of the system.
Thank you.
