This is likely to be either a driver issue Have you that you know of recently updated any drivers.
Do you have any driver update software on the computer. For instance a program from something called DriverDetective will offer to automatically detect out of date drivers and install new ones. THESE sort of programs frequently install the wrong driver. It is not apparant until you Shut down and reboot that there is then a problem.
Have you installed any new hardware The Dell Dimension E520 is a desktop is it not.
Alternatively it may be a memory issue-are you familiar with the inside of the case and the location of the ram.
WILL the computer load Windows in any mode.
Do you have the XP CD.
Did you experience any other problems prior to the BSOD for example, Windows freezing and not being able to shut down as normal and forcing a shut down on the power switch.
