Is this monitor broken

[rhino1616]

Hi,

My girlfriend has been going crazy trying to use her computer. The monitor is constantly going sqiggly & then back to normal. She cant properly surf the net & use her programs. I connected my monitor to her computer to see if the same thing would happen & it did. My monitor started acting the same way. I reconnected her monitor & reset the refresh rate, but no change. I checked for any magnetic interfence around her computer but there is none. Her father has a solitaire game installed on it that he's been playing for the past year & now when he plays its the program that causes the mostly distortion in the screen. Im not a computer tech, so Im assuming this might be a videocard in its last days of life. Her computer is a P3 900 w/soltek SL-75LIV fully intergrated motherboard. Does anyone know what this problem could be? Is it the monitor, the video card or something else?

Thank you

If the problem showed up in your monitor too, it's the video card or some sort of interference.

To rule out interference, take the computer and hook it up in another room using a different surge protector and your monitor.

I diagnosed a problem like this two weeks ago for a friend and it was indeed the video card. Try swapping out a video card from another computer.

It might be the monitors power supply aswell.
