Hard to tell if its 3 or 4 beeps in a sequence, but these are the most common beep codes.
1-3-1 through 2-4-4 | Memory not being properly identified or used |
4-3-1 | Memory failure above address 0FFFFh |
If you experience any of the following beep code errors, see
Contacting Dell for instructions on obtaining technical assistance.
