Male moniter plug on both moniters(every one in the world) and motherboard

Verify four things:

1. You are not plugged into the onboard video VGA port

2. Onboard video is disabled in BIOS.

3. Power is actually being applied to the card(make sure the fan spins up)

4. Reseat the card and make sure it is seated properly.

What I would try is to uninstall all Asus software and go to the above link. The link has a download tab where you can enter you operating system and it will give you the drivers for your board. It Has an Intel H55 chipset. so amke sure thats updated as well. I don't know how you have the board hhoked to the moniter/lcd but make sure it's plugged in when you download. If you have some sort of control center or place where you can look at what moniter the board is recognizing you may have to click on the moniter you want to use. Whenever you change the video output, you have to resatrt each time you change, then look at moniters recognized. If you have system restore, you may have to hook it up the way it was when(?) working then try to change outputs. Asus does have support. You may try http://usa.asus.com/. Telephone (510)739-3777

usually its the 15-pin blue male connector on the back of the motherboard.

Try this link about the beeps,,,

Download the user's manual. Usually such information is given there.

try to remove the motherboard from the casing and see it if the have some capacitors or any circuit distroy. use other mother board for testing chek your hardware one by one maybe some of your hardware devices damages.

are you using an add-on video card? If so, then go to BIOS and enable it.
