I disabled the hard drive and then enabled it. Now my computer is not functioning properly.
Cannot open pdf files. All printers are gone. Cannot Add Printer or install printer drive. Some sites (https) don't open in IE while they do in FF. Windows Media Player does not work. I get a warning that syas: The file wmp.dll has a version number 11.0.5721.5280 where 11.0.5721.5230 was expected.
Thanks rolli59 for your answer. It worked.
I cannot find the gold cup to sellect it as the best answer. I guess because it was 6 months ago (I think I'm a little slow, aren't I!!!?). That was the only answer I got anyway.
