I can't see most things on my desktop. For example, when I right click to change settings, the box comes up in black. The writing is also in black (I assume), so I can't see anything but the black box. Anything that should be grey (like the borders for explorer or Word) or white (like the address bar) are black and can't be read. Any suggestions on how to correct?

Have yo tried finding your way into the desktop theme settings? I know if its all black its a bit hard to see where you are going but if you can reset the theme back to the default one it may help.

Thanks, that's what I did (I used a screenshot from a working computer) and it worked. I aprreciate the help.

Glad to help.
