*Pawing a Rosary in thanksgiving!*
I feel that I have, at last, succeeded in rehabilitating this computer -- only now, have I finished reinstalling much of the degraded software. I had to create a new user-account, migrating info from the corrupt one; and repair the registry. Thank God, that I use an SBC/Yahoo Browser because IE was utterly non-functional. This is the only time my pc has been affected thus -- unfortunately, power failure is all-to-frequent in my (red)neck of the woods.
That's what I get for having disabled the System-Restore function in favour of glutting my computer with more music files.
