I have a Gateway E4100 desktop with XP pro SP2 installed. I added more memory to it and when I started up the computer it started beeping. Everything seems to power up(cd-rom,cd-rw,hard drives,fans) but it's not sending a signal to the monitor. I know the monitor is good and I plugged the computer into another known good monitor also, still nothing. I removed the new memory and restarted and still the same. Anyone have any ideas?

Hi and welcome to D-A-L

how many beeps are you getting?

when fitting the extra memory were you careful with ESD?
