Weird screen corruption issue
Posted: Mon Nov 07, 2011 2:40 pm
Here's one I've never seen before.
My PC at work is a Dell Optiplex 780 with WinXP Pro, and includes a GeForce 9300GE driving dual 2700FPb monitors from analog. Desktop is spanned. When the system uptime grows into the range of a week or more, the monitors will start to develop these faint, whispy ghosting patterns that gradually grow in size. The pixels will still transition fully to white or black, but when displaying intermediate colors, the patterns emerge, almost as though there were smears or smudges on the monitor. Everything is fine after a power-down and reboot. I've seen this at least twice that I know of, so it wasn't just a random fluke.
Anyone got ideas? I don't have administrator rights on this machine so I can't be certain about the driver version, nor can I update them. Mostly, I'm curious about what causes this, and whether it signals an impending hardware failure. If so, I would like to have that info available to file a help ticket with IT, as I don't want the GPU to just quit on me one day.
