Computer wont post...not the normal symptoms

[josboh]

Ive dealt with non-posting computers before. Usually I can narrow it down to the PSU or Motherboard no problem.

However, my computer isnt posting and I cant figure it out. Here's what happened. I was on the computer surfing the web no problem.
First the keyboard(ps2) stopped working (the mouse worked-usb). I restarted and the keyboard still didnt work.
I restarted again but the computer wouldnt post.
With everything still connected the disc drives and the hard drive were all blinking.
The motherboard (asus p4p800) still lit up green.
All fans.
I disconnected everything. Except the video card, memory and processor. Still nothing.
Reset the cmos, still nothing.
Can the motherboard be bad, but still light up green? I see no reason why the processor would have gone bad...

Anyways, I hope that someone here can help me.

there might be a short causing intermittent failure that will soon fail altogether.

are you talking about the green light on the mobo? usually that just means its getting 5V standby power from the PSU. you might wanna try a different PSU if you have not already.
