Do the keys themselves all work? I bet one of them is a)busted b)stuck. Try the OTHER alt key, as ctrl-shift-esc still works, the ctrl is ok. Make sure the del key still del's. Give each, and I'm serious, a good hard poke, do this to both alts, both shifts, both ctrls, the tab, del and esc keys - as hard as you can without finger damage. Simple solution escapes us all.
