I have upgraded from Win 95 to Win 98. Everything went fine. I then went into internet and started to download some files. THEN, the computer crashed. I re-booted and found that in place of my windows icons I had black squares, and also for my folder icons. I can still launch progs etc, but do not much like looking at screen chess like board view. Does anyone know what's happened? Even when I attempt to change the icon from the properties screen, the icon is selects but does not change the on-screen black square. A corrupted file or is it more sinister? Help.
