windows 2000 corruption, help!

[Henri]

When I click on internet explorer, my computer, explorer,
or "start-settings=control panel", the screen goes blank
for a monent (with the windows background color)and then
simply returns to the desktop as though nothing had
happened, no error messages. We think this happened when
the user got a corrupted active desktop message, but do
know if that is true, just included it for info.
I have tested the drive for viruses in another computer
and done a upgrade of windows 2000 on a ghosted copy of
the hard drive. (I set the original aside) I have used the
ghosted drive in another computer and reconfigured windows
for it on that machine but still have the same problem.
Any ideas, short of starting over.

It turned out to be an issue of spy ware redirectors
screwing up IE6, used adaware and hijac this to fix it, be
careful with hijack this as many of the found entries were
ligit....
