display, or my video card.

  1. I have a 5 year old ViewSonic E790 19" display, and a Geforce Ti 4200 graphics card.

    I have updated all the drivers.

    Once in a while the display corrupts, showing patterns that look like large pixels. Sometimes it appears as a series of vertical lines, each 1/2 to 1" in width.

    Rebooting won't fix it, I need to power off the computer and power on to recover.

    Any thoughts as to what it is?

    Instead of rebooting have you tried turning the monitor off, then back on after a few seconds?

    Yes. The corruption happened again last night. Turned off the monitor, turned it back on after 10 seconds, it looked the same.

    That makes it the vid card I think.
