Yeah, that screenshot looks perfect on my machine.
I think it’s your display driver, especially as you note it’s not localized to one application and is apparently not transporting through print to screen.
First, turn your monitor off and pull the display cable out of the back of your computer. If you have canned air, spray the internal connections, to get rid of any dust. Re-connect, being sure to seat the plug securely and screw the locking screws all the way down.
Then, if that didn’t help, try upgrading and, if necessary, re-installing your display driver. Check your version of DirectX and, if possible after upgrading the driver, upgrade.
I don’t imagine Norton is messing things up, but as a rule, the only Norton software I use is Ghost. The rest is junk and impossible to uninstall. Neither here nor there, I suppose.
You could also have a virus that has used a buffer overflow to right over part of your hardware configuration files.
