Ok so my brother got a pc with windows 98 on it awhile ago.today I got rid of a bit of spyware and such. Later in the day we turned it on and it wanted a registration code. So I looked online and found one. Once we got on the desktop all it was, was a white screen. So we tried several times and all we got was a white screen (you could also see the mouse). Then an error message comes up saying internet explorer closed.....anyone know how to fix this?
