Having problems with your Compaq PC Desktops ?

Compaq Presario sr1720nx has wavy video. You can see everything okay it's just that the video is wavy and kinda taxing on your eyes. It does this with every monitor I hook it up to. I've also tried a different power supply still same results. Tried disconnecting DVD drive and any other devices not needed for boot up and still doing the same thing.


Answers :

Is it wavy all the time or just when windows is booted up? Try booting up in low res mode or safe mode and see if the problem continues. What is the monitor refresh rate set at? Try lowering the refersh rate. The on board video/video card may be going bad. Lowering the refresh rate may reduce the wavy picture. If it has a video card you could try installing a different card. If it has onboard video try installing a video card. Make sure you drivers are up to date.
