Blank screen when Gateway GM5664 desktop turned on

[mk2233]

Hello,

I'm trying to fix my friends Gateway GM 5664 desktop computer.  He was told by a local pc shop that it needed a new motherboard.

I went ahead a bought a new one and installed it.

My problem is once I turn the computer on I hear the initial beep and all the fans start running, normal hd drive sounds, mouse & keyboard work but I have a blank black screen. So I can't see anything on my monitor (monitor says no signal). The monitor connection to the pc is secure and the monitor has been tested on other pc's so I know it works.

Can someone let me know what the issue might be?

Thanks is advance.

Many things can be at the root of this type an issue. Have you tried another video card yet? truenorth

The monitor is connected to the vga connection on the motherboard.  There are 2 other cards on the mb.  One is for DVI input and the other is for tv input.

Input ? ?...you mean output right ? ?

[mk2233]

Right output.

I would power down both the PC and the monitor and try the DVI connector then...
It's a good possibility the onboard vid is disabled because there is a vid card installed...which is how it's normally designed to work.

I don't have a dvi cable at the moment.  If I remove the dvi card would that make the onboard vga the default?

I'm going to try that and see what happens.

Yes...it would.
You may want to remove both cards to test...dont know what kind of setup he was runnin...

It worked!

All I had to do was take the dvi card out.

Thanks Patio!!
