My PC was working fine until about 3 days ago, when I started having problems with my keyboard. I first noticed that it was acting like it had no power until I plugged in the PS/2 port again. The second time this happened, it completely stopped responding.
Since then, I have tried another PS/2 keyboard as well, but the keyboard LEDs flash randomly and there is no response to any key. Thinking that my PS/2 controller may be shot, I tried a known working Logitech USB keyboard. On the USB port, it does not enumerate the device. During POST, the LEDs come on once, but no key response. During windows startup, the LEDs keep flashing, like its continuously trying to enumerate the device.
Other things that I have noticed are that the BIOS does not stop on a keyboard error, although I don't know what the current BIOS setting is. The device manager does not show a keyboard installed, hidden or otherwise. I even performed a BIOS update, made no difference.

My specs:
Intel P4 3Ghz
Intel D915gvwb motherboard with integrated graphics
512 MB RAM
Windows XP SP2
