in defense for bobo, yes thermal expansion CAN and DOES cause cards to improperly seat. I'm not saying the are in there loosely, but the pins dont have a proper contact. So, instead of having him going out and buying a bunch of crap, how about finding a cheaper way first. Try to reseat the vid card (yes, again) the memory and processor. also remove any uneeded peripherials. basically, make it bare bones with ONLY the vid card, memory, CPU and HDD attached (yes, even take the kbd and mouse off) you wont get far, but maybe able to illicit something. see what happens. if you have 2 seperate mem dims, then use one mem stick and then the other.
If you argue with an idiot he will drag you down to his level and beat you with experience.
