I have an ECS PT800CE-A Motherboard Running a Prescott 3.0e processor.
The system has been running fine for two years. Two days ago I was surfing the web and the monitor went into standby mode. I couldn't get it to come out of it. So I rebooted the machine. The machine will turn on and sit there with a blank screen.
I pulled everything but the ram and video card. Still no luck.
So then I pulled the agp card and installed a pci card. I have video now but it still is not posting.
It is stuck at the screen telling me the installed processor and to hit delete to enter bios.
I can't enter bios because the keyboard is not working for some reason either. The keyboard lights blink when I turn it on.
I am not getting any error beeps from the board. But if I remove the ram it will beep.
What could be the problem? I have tried two power supplies so far.
This just happened out of nowhere. Nothing was changed or modified.
It is a ps2 keyboard. The lights come on initially like normal then they go out. I tried plugging in a usb optical mouse and it lights up and stays lit. So I have usb power. I'm beginning to wonder if the 4 pin 12v is going bad. Maybe it is not passing enough voltage. HELP!!
