When you get a (worldly known) blue screen of death, it's usually directly related to a driver / kernel / memory issue. You need to find out what it says on the blue screen, usually something like.... "caused exception in module BLAHBLAH.DLL" or something similar. Some of the more common ones are Kernel32.dll, mup.sys and pretty much any dodgy driver you care to mention.
If you can be more specific about the type of failure, you may be able to fix it. Note down what it says on screen (not including the hexadecimal numbers) and post back if poss.
