Bleh, dell and alienware.
Years ago a guy i was seeing tried to buy a used alienware laptop, was a good price. But it managed to lose it's drivers for the screen SOMEHOW every time you turned it on. You can't just download alienware drivers from anywhere, and they wouldn't give them to us because we weren't the original owners. he thought he could be clever and buy like, a networking cable from t heir website to become a customer and get access to the drivers, but it didn't work out. wound up taking the damn thing back to the pawn shop.
You don't have an old windows xp disc laying around or anything? Or if the CD key is on a sticker on the side of the tower you should be able to download that appropriate version of windows as an OS disc rather than using a restore disc or factory restore (which probably includes a cubic ton of bloatware anyway)
