Answer #1
these are called artifacts
they are either caused by bad drivers, overheating, swollen capacitors or bad power supply
if these artifacts don’t showup before windows then its bad drivers, you can uninstall them through safe mode
Answer #2
I have no idea from your pictures except that you may have Vista and XP both installed…a picture is worth a thousand words, but sometimes even a few words help
