P4S800 no display and beep code

Not open for further replies.
I have a an Asus p4s800 mobo, i carried it downstairs then back up and plugged it back in and the screen was blank and it had one long beep then repeated forever. I checked the graphics card and put it back in place. I unpluged everything from the mobo and it beeped 1 long and 3 short. When it is unpluged and pluged back in it doesnt beep,but still no display. but after your restart it has no display and beeps. I took everything out and put it back in place and still is doing it, any ideas?
anyone know what these beep codes could mean, i have no clue what the bios are since you cant get ANY display not even bios.
I also checked the power supply, no problem there.
Thanks in advance for any help!

Remove your RAM and clean off the contacts with an eraser, reinsert.
Repeat with your video card.
