I believe it is, but here’s what happened:
All of a sudden one day my monitor went black and then popped up “No Video Input”
Restarting the computer brought it back briefly but before I could even get to device manager it went out again.
I tried using new cables and tested another monitor (exact same model) and all the same response.
I inserted a PCI video adapter and booted up. Everything seemed ok until the next day when the exact same thing happened.
Now however, there seems to be no power to the keyboard, and the network port is not lighting up. All of which are integrated into the motherboard.
The fans and hard drive appear to still cycle.
I’m guessing that whole part of the motherboard (containing the audio, video, PS2 ports and network) is now kaput.
Your guess too?
