my monitor has this thing, it goes into power save sometimes. when i plug it into my new computer, it just says "no input signal" so idk why there isnt a signal.
Lol, yeah. I don't know of any tests you can carry out on the motherboard of than that to see if its not working. It sounds like it isn't - cause I can't think of anything that couldn't be doign it. Do you still have warrenty on the Motherboard?
