I am trying to fix my sisters computer but am getting no where. At her house when she turns on her monitor it says
VGA input
No input signal
Recommended settings 1280x1024-60Hz
then it says monitor going to sleep.
She has one of those flat screen monitors and a Hp Pavillion a 1712n running Windows Vista Home Premium

So I bought it over to my house and hooked it up to my Dell monitor and all I get is a blank screen.
I have a Dell monitor and computer running windows xp home but I am only using my monitor with her computer.
Can anyone help me please?
