vista shuts down computer for no reason?

Question

im on a brand new compaq (less then a month), and at least twice a week vista just shuts down my computer when im using it for no reason.
Its not like a loss of power, it goes through the normal shut down procedures. It wont do it for any particular program, ill be in photoshop, and it will shut down, then ill be in firefox and it will shut down.
I consider myself to be somewhat knowledgeable when it comes to computers, ive previously built and modified computers in my life, and i get the basics of the windows operating system. I checked the cpu heatsink and it was cool to the touch, i checked the connectors throughout the case, and everything is seated well.
Ive run every type of spyware, virus, worm detectors and have come up clean. ive run compaq maintenance, and it says that everything is good, no corrupted files or missing data.
My father has a toshiba laptop with vista 64 and has had no probs. Any ideas?

Answer 1

There very well could be a short in the system that only appears at certain times. I would take it back to wherever you bought it and start asking questions. Also I have had a couple of people tell me that Vista is prone to problems, Microsoft just hasn't worked out all the bugs yet.

Answer 2

Call Compaq tech support, they will help you.

Answer 3

do a driver check

possible driver problem

or ram issue
