ASUS P4S800-mx MB with Intell CPU that will not boot

I have a ASUS P4S800-mx MB with Intell CPU that will not boot.  Fans, lights, all power up. Computer was on and I went away and then came back got a no sync on Monitor.  Tried different monitor, Tried new power supply, changed MB Battery, reset CMOS.   The lights on the CD DVD's stays green and there is no Hard Drive Access.  I removed all device except KeyBoard, Mouse, Monitor.  Still no boot.

Do I have a bad motherboard.

When you switch it on, do you get a beep that didnt come before? Are you using the integraded graphics or do you have a gfx card? If you are using a gfx board, try removing it and connecting the monitor to the integrated graphics. If you are using the internal one, try connecting a gfx board.

There is no beep when I turn the computer on.  We are using an integrated graphics, I will try using a gfx card. thx

Changing gfx card did not help.
Once when I destroyed my CPU I got the same symptoms as you. Do you have access to another cpu you can test with? By the looks of it I`d say that its most likely either the cpu or the motherboard
