I was monkeying around with pc screen resolution settings. I have pics that when I attempt to use them as a screen saver, they are just a small pic in a box instead of full screen. Well, in the process, I set something to 256 bit high color instead of the setting it was for the longest time (will later figure out what that was). Something popped up and asked if I want to change something and I said yes. Now I got a screen with blown up psychedelic swirls and everything is huge (too huge for screen to handle). When I click on my user account, my screen saver pic looks like a negative, only with color. I tried and failed numerous times trying to use system restore, something is blocking it. Any help is desperately sought and well appreciated. thanks!
