|Looking for for some help in getting my 4550 up and running. It powers on and I can see the Dell logo on the monitor. Shortly afterwards, the monitor goes dark and I can hear that the computer is not doing anything. I can get into set-up but not sure what I need to do once there.|
There are no diagnostic beeps. The four diagnostic lights on the back on the cpu are all green.
I added RAM a little while back and it did work after the installation, so I don't know if there's any relation. I tried to reset to default settings by usgin the ALT "F" command in set-up, but that didn't do me any good. Don't know much about computers, so I'd appreciate any help.
