Monitor Going To Sleep!

Hi wonder if anyone can point me in the right direction with this???

Just bought a new pc (hp) which is running windows xp. Set up was pretty straight forward however, half way through doing something on it (95% of the time) a message appears saying that the monitor is going to sleep and The PC crashes and goes to the blue screen, where it says PAGE_FAULT_IN_NONPAGED_AREA

The computer then displays the hp opening page and jumps into what i can only descripe as DOS format and says that the computer has shut down to protect my computer and do i want to run in safe mode, last known configuration or start windows normally. I have been shutting of the machine from the main button as only way i can close as the monitor just goes to sleep.
Not on the net at home so could not be a virus i have picked up??

PLEASE HELP!!

First off as it is a new computer I would return it and demand a working machine.

That being said if you want to try and see what's happening start here:

Look in your Event viewer: rt. click My Computer then click Manage then Event Viewer.
Or: Administrative Tools/Event Viewer or Start/Run/ eventvwr
Open the system as well as the application tabs & look for red X errors. Click error line for details.
Post back the source & event id & Description especially of errors that seem to coincide with this issue.
Also check the Information lines that might coincide with this issue.
