I left my computer sitting unplugged for too long and the battery died. I charged it for an hour or so then went to turn it back on and was greeted with a grey screen and 3 beeps. After some research, it seemed like the solution was likely the ram needing to be reseated. Long story short, I've tried every possible combination of my 2x2GB and 2x1GB ram sticks. Both slots work fine. All four ram sticks work fine individually (in both slots) and seemed to work in a 2+1 combination, but the 2+2 combo results in 3 beeps again. Any help??
