When you get an error like that listed in your subject line, and you then
switch to winfile, it should be solely for the purpose of diagnosing/fixing
the original error.

Please refer to http://tinyurl.com/yl9y62 and see if any of those articles
comes close to describing what you are experiencing, and then use WinFile
*only* to address the original problem. If you still have problems with
WinFile (can't even use it for this limited purpose) then post back. Much of
what is recommended can just as easily be done from a command prompt,
without loading Windows at all. Include *all* of the possible factors that
may be at play. Like have you recently installed any new programming or
program updates? Have you been into the guts of the machine? Added/removed
any hardware? Had any other odd problems recently? Messed with Virtual
Memory or used any "RAM Optimization" utilities?

You say you ran Scanreg. Did you try restoring a registry backup using
Scanreg /restore?

From a command prompt only startup, run the following:

DIR /s explorer.exe

What comes up? Please report *all* of the details. Note that exact wording
is important. For instance, your subject line left out the word "you", as in
"you must reinstall windows". Searching for articles addressing an issue is
much easier if we have the exact wording and can thus use exact phrase
search parameters.

Personally, I suspect that you have hardware problems that are causing both
of these errors. But we're seriously lacking in sufficient details to make
that call.
