You might try removing and reinstalling the card in the slot.<br />
They do sometimes work loose even just by creaping from heat-up cool down cycles.

I pulled the card and put in another one, which cured the problem. &nbsp;The old one had a nice, big bulging capacitor! &nbsp;

Today, for no reason, it seemed to lose any color over 256 (because some of my icons are gray) and at anyrhing over 600X800, it shows double wallpaper.  If you click on one of the Windows standards and ask it to "center," (I'm looking at Zapotec right now) there are two of them, neither quite centered, lined up like the dark squares of a checkerboard.

Double pictures windows display higher than 600x800

A desktop computer is a personal computer designed for use at a single location due to its size and power requirements, usually by one person. The most common configuration has a case that houses the power supply, motherboard, disk storage (usually one or more hard disk drives and optical disc drives); a keyboard and mouse for input; and computer monitor and printer for output. The case may be oriented horizontally and placed atop a desk or vertically and placed underneath or beside a desk.
