Hi. I was clearing things from the C drive when I think I deleted something important. When I restart my computer the screen's resolution became either 800 by 600 or something else. When I try to change back to my usual 1024 by 768 pixels it would not change. Any ideas? =/

With your mouse right click on your desktop follow down to properties and this will bring you to the display properties where you can readjust your settings.its pretty self- explanatory when you get there...

You may have deleted part of you video drivers, depending on where you were deleting from. If that is the case, then you will have to reinstall your video card drivers.

If you don't have a driver CD you will need to get them off the internet.

Try going back in 'system restore' before you deleted things, and see if you can't get your settings back.
