I have an alienware laptop with a Radeon 7500. Two things happen, first after about three or four minutes games that are graphics intensive (just about all of them) slow down to about 1/10 the speed, and stay that way. Generals to Red Alert to CS. My 300Mhz Celeron runs them better. Secondly I get the same blue screen of death, with the infinate loop/ati2dvag error. Both Alienware and ATI customer support suck my balls. Alienware just wants to give me drivers (they have a special one for BF1942) but they don't fix the problem just decrease its frequency, so it only happens about once out of 5 times I play, instead of EVERY time. ATI does nothing but send automated responses, that don't answer my questions. If a 3.06 Ghz/1024DDR laptop can't run Red Alert 2 or Counterstrike, but a 300Mhz Celeron Desktop can, the world is one ****ed up place.

Oh, yeah and I've left everything as the factory set it, no overclocking or anything, and it always sits on a table when playing. So if the bugger overheated I have no clue why.
