A MV540 is a display which can be used on many machines.

Identify your computer first. If the computer is some HP/Compaq the drivers are over at www.hp.com

If you have some HP/Compaq, it should have some restore CD that would just fix the machine. If not, then its also worth noting that unless you've changed the video card, identifying the video card is not a good idea. Looking for a videochipset driver may not work so well.

What machine is this?
