HDD LED constanty blinking

[CheapBastardo]

I just got an E-machine from a friend. Power up, hdd led amber blinks constantly. The fan in the PSU is fine but the CPU fan and hdd are not spinning. All the jumpers are set correctly.

Could it be a bad motherboard? I've tried a known good PSU but the one I've tried doesn't have a P8 connector and the same thing happened.

Please advise.

Have you tried disconnecting the Hard Drive?

Did you try clearing the CMOS?

disconnected the IDE cable from the mobo and the light stop blinking and hdd start spinning. Diconnected cd-rom ide cable from mobo and cd-rom ejects. Took out the cpu fan, try it on another computer, works. So, I guess it's the mobo that's been causing the problem. I tried resetting CMOS by taking out the battery, put it back, but that didn't do anything.
