Okay guys, he had the virus and to get rid of it he reformatted. The current issue is that he has no start bar.
Mate, you haven't said what operating system you're running so it's a no-starter so far anyway.
Try mousing into the corners to see if the start bar has been set to 'Auto Hide'. If it now pops up, right click on it and uncheck 'Auto Hide' (2000/XP[?]). It might just be really small. See if clicking on the edges and dragging thme out does.
I *think* XP has some fugly options enabling you to hide the start bar and program icons completely. Try right clicking on the desktop and have a gander at the options that brings up.
Good luck.
