The error message merely gives the path to the minidump file which is created when there's a crash. The minidump file is not much help to us because we won't know how to read it.
Click Start, Run, type eventvwr.msc and press enter. This gives you the Event Log. Highlight the System Log on the left, and look for errors with a red cross on the right. Double click the error entry to read the details. The time for each event is recorded, and you can work out which error has caused the crash.
Even that entry is quite often impossible to decipher, but sometimes it may give an indication of what's wrong.
Also, right click My Computer, select Properties, Advanced tab, Startup and Recovery, Settings. Under System Failure, untick the box for "Automatically reboot", click OK, and OK. Next time a crash happens, you will get the Blue Screen of Death, with details of the error. Write it down the error message (although it should be recorded in the System Log anyway).
