Replaced new motherboard and can't see anything on the monitor

[lossguy]

Hi

Can anyone help me?

This is the spec
CPU C2D
Motherboard ECS P4M890T M
SOCKET 775
2G RAM DDR2
8600GT PCI-E
PS Antec 550W SLi

I builded a computer 2yrs ago and I decide to replace the motherboard. I bought a ASUS P5K-E/WI/FI. I installed and follow the guide connect everything, plug in power and you will see the LED on the motherboard lite up but somehow I can see anything on the monitor. I call ASUS and they told me to all unplug the fans, still can't see. Removed the RAM still can't see, so they ask me to try new Power supply I did still can't see. Finally they told me to removed everything except for the CPU and CPU fan to see if I hear any beeps. I try that and no beeps.

Remeber CPU's used and brand new ASUS MB P5K-E/WI/FI.

Please help me someone.

Thank you.

Take the mobo put of the case and try running it that way.

Try clearing the CMOS in case it got scrambled. There should be a jumper on the motherboard to do that, if there isn't or you can't find it then pulling the motherboard battery out for a few minutes will achieve the same result (unplug the power lead as well).
