Thanks for the help!!
I'll have to remind myself to remove all drivers for a part to be replaced BEFORE replacing it.
Anyway I went with the clean install with a new HDD. It seems someone
was indiscriminately surfing because they couldn't play their MMOG's when the 9550 went kaput.
Too much Junk. Too tired to clean.
I'll keep the file in storage if I ever switch back.
