Having problems with your Dell OptiPlex GX280 PC Desktop ?

Plugged a different computer into a working monitor and get nothing but screen filled with pixwls or dashes


Answers :

Is the monitor connector VGA by any chance? Check that none of the pins where you plug the cable into the PC are bent. If none are bent, ensure the graphics card is seated correctly. Loose graphics cards can cause garbled display. Try unplug the graphics card, unseat from the motherboard and re-seat.
