I am far from knowedgable about computers. The other night when I came home and turned on my computer all the icons on the desktop looked differently, etc, etc. It now displays all pages on the net, e-mail, etc grainy and with much less color. I went to the appearence settings and they were set down at only 16 colors and the lowest resolution. Upon increasing both the computer prompted a restart for setting to take place and when doing so and returning to those settings it appears the settings dont change/ respond to the settings change I made. My pictures stored on the computer now look basically black and white, etc. Is this a sign of the graphics card failing or am I missing something?
