I have the same problem and I also have a MSI mobo.
I don't get beeps but I do get the blank screen..I've switched my graphic card with another and even my RAM sticks with another pair I know that works.
Does all your drives turn on?
Hmmm.
I did the battery thing.
I'll try the monitor.
As for the keyboard that might be right because it is a ps2.
I have a mouse that USB and it works.
I also opened it up and looked where the computer turns on..You know the power cord to the mobo..it had some blue goey stuff on it.
There all connected.
It's my friends computer.
He broke his other mobo so he got a new one.
It's worked before but they moved and it's just been sitting around and after they decide to use it again it's broke.
Well...no video anyway..
Ok so I have this eMachine and I'm not entirely sure whats wrong with it.
I do know that the mother board has been switched out.
It's a MPI.
Everything turns on drives,fans..
The keyboard doesn't turn on neither does the monitor.
Any ideas?
