[Users] Troubles Shooting of (failured) Hardware Components?

[Demetry]

Hi all.

Anyone here that is a hardware freak?
I need a expert tip. My Vista chrashes every times when i am working. I 
need a tool to analysing and detecting fastly and simply the troubles 
with my hardware components.
Vista says me that's giving problems with a device driver. But I don't 
know which one is responsible for the horror crashes. The Device manager 
says me that gives no errors...
I am very despaired and apreciate your helps.
Thanks.
