i am just going to use a debugging kit that Microsoft lets you download to test the dump file, to see if that comes clean, if it does then it was just a freak incident.
i can start up my pc normally after the error, and recently i did remove 4 gb of ram, because it had a different problem which is fixed now. i did clean the ram slots for dust, but not video card, i will just check with memtest and update drivers.
if it is a .exe file, why don't you right click it, go to properties and look at which folder it is a shortcut to, then delete the folder (unless it is a windows folder).
