I've had that blue screen happen to me on desktops. Usually when some idiot got past my firewall or antivirus software. Always had to scrub the HD and start over.
I don't like Dells, Packard Bells and, now, add Gateway to that list.
IBM and Compaq are my comps of choice. Easy to add memory or cards or HD's to.
Hope you solve the problem without it costing a bundle. :)

Let me introduce you to my multiple personalities. :)
