Flashing Amber Power light


Beta member
Ok, here is the info...

Dell Optiplex GX150
-Dont know what it is running, but it doesnt really matter..

Anyway, trying to power on the computer, all i get is a flashing amber light from the power button. I am pretty sure its the power supply, as I have disconnected everything on my computer (HD, floppy, CD-Rom) and I still get the flashing light. The first couple times I powered it on, I got a clicking noise from the on board speaker, but that has since disappeared. Anyone have anything to make me think its not the PS?
Also, when the monitor is plugged in, there is an amber light on the monitor as if no video is being sent the the monitor.

**Edit** I have not installed any new hardware/software.
