I had this fault arise, after checking the memory and as far as i can tell appears to be OK, I followed the Dell recommendation and replaced the main board, but the fault still appears? any help would be greatfuly appreciated.
1-3-2 Beep error indicates no memory installed. Dell 1800 Info I assume you have memory so possibly the main board is an issue or RAM. Have you tried removing all RAM and adding back in?
Was the replacement board a new/refurb Dell part?
