I have an Acer monitor that periodically gets filled with green lines and some blue patterns.
What might be causing this problem and how do I fix it?  The only way I can get rid of it is to reboot the computer and then it is okay for a while but it does come back.
thanks,

Most likely your video card or the monitor itself is going bad. Do you have another monitor to test with or know someone that has a spare in the basement?

The best way to determine which one is causing the issue is to switch out either the card or the monitor with a known good. Once you know for sure which part it is, you can replace it.

Does this happen at regular intervals or is it random ? Does this happen when the Video Card (if present) is stressed ? I mean does this happen when u play games ? or perform any task that utilises GPU power ? JMILLER1979's advise would be of great help to u, in order to isolate (vdo card or monitor) Check if the VDO card or the vents of the monitor heats when this happens.

There can also be a problem with the RAM of the computer, if the video card is using shared memory.

There is free software, memtest 86+,  to test the RAM, or maybe your computer has a built-in diagnostic mode that you can activate on the boot screen with a Function key (eg F10).

Green lines and blue patterns...
if you have a spare video cable try it out to make sure your cable isn't the fault.
(And check if connectors on both ends are undamaged)
After ruling that out move on to testing another screen and then video card.
If this all didn't help so far your last bet might be a driver issue (corrupted dll's or whatnot).
