BLUE SCREEN

This Stop error, which can be caused by either software or hardware, indicates that a kernel-mode process or driver attempted to access a memory location it did not have permission to access or a memory location that exists at a kernel interrupt request level (IRQL) that was too high.

I had the same problem. I checked everything and put my harddrive in to the a other computer. Samething. So I just reinstalled windows. Try reinsttalling. Or if you have a secand computer try putting the harddrive there. and save your data to the computer and delete the rest.

This is probably a hardware issue, possibly even the hard drive. You should have a diagnostics CD from dell or you can download one from support if you have lost it. Run it on all hardware.
I take it your warranty has run out. If it hasn't, use it. I have many Dells here and have found their support for small businesses to be excellent. (Cannot speak for home owners though)

Is there a file mentioned after the error?

When you get a bluescreen you should power off and then resatart after a short period (5 seconds or more) rather than just re-booting.

Searching MS Xp support I found a couple of possiblilites, but a file in connection would probably help greatly:

You have a driver incompatibility.

Disable the driver booting in safe mode or use this utility that fixs it:
