How do I reset my computer to normal icons and 1680 X 1050 pics and 16 color qua

[ladyfirefighter63]

I can't reset my desktop monitor. I tried to check my email this a.m. and my Icons were humungous, like the whole screen was stretched. I checked my display settings and it was reset to 640X480 Pix and Highest(32) color quality.. It needs to be 1680 X 1050 pics and 16 color quality. the problem is the display settings won't show up so I can't apply the new settings on anything, theme, background, nada. nothing. What do I do????
