Hey, I was messing with the RAM settings in my ASUS BIOS (possibly another settings for the CPU). I thought I knew what I was doing but obviously not and saved the settings and restarted and now the computer sounds like its starting up and all, but nothing comes up on the screen (even if I plug the monitor into the MOBO output) and it beeps at me. Beeeeeeep beeeeep beeeeeep beeeeep Just over and over and over. PLEASE HELP!

Try resetting the bios.
Turn off the computer, (make sure you unplug it too). Locate the bios jumper ( 2 or 3 pins) and reset it as per the motherboard user manual ("clear cmos position").
Or, remove the battery for 20 minutes then replace it. (make sure you unplug the power supply)

Continuous Beep No Power, Loose Card, or Short.


thats the one but there are no shorts, it has power, all cards are in and everything but I'm going to take everything out except the one hard drive and see if anything happens. Does the motherboard have a little battery that needs replacing sometimes... I think I read that somewhere but I've never had a problem like that.

PLEASE if anyone else has any ideas please post them

open the computer, look for some pins that say "clear cmos"
How many pins are there.
Is there a jumper on them? (A small peice of plastic over the pins)

PROBLEM SOLVED

This particualr model of board does not even have a jumper to clear cmos with. you have to take out the battery and short 2 points on the board with a screw driver to clear the bios. Thanks for your help sarah you did move me closer to the solution.
