Hi, I came here in search of help with my Dell Demension E510. (Windows XP) When I turn it on it makes a kind of grinding sound, and wont boot. There are the numbers '3' and '4' illuminated on the front of the tower. (I'm not sure if they were there before.) I can't remember if it beeps or not.
This problem occured after a BIOS upgrade. Can someone pleeease help?
