Windows Explorer Error in My Computer / Explorer

[Schoolies]

I have Windows XP (SP1). Now whenever I try to copy/paste, right click, or use the File menu in My Computer or Windows Explorer I receive a Windows Explorer Error.

"Windows Explorer has encountered a problem and needs to close. We are sorry for the inconvenience." AppNAme: explorer.exe AppVer: 6.0.2900.2180 ModName: shellext.dll ModVer: 1.0.0.1 Offset:00001e31.

I must be "inside" one of my drives for the error to pop up. If I just double click My Computer, I can use the file menu and right click. I tried installing Service Pack 2 hoping it would fix the problem, but it has not.

Any help would be great!!

Have you ran Adaware & Spybot? Scandisk?

Yes, the computer is virus free and spyware clean. I've ran adaware, spybot, TrendMicro sysclean, AVG antivirus scan and Norton Antivirus corp ed. (which I don't think was working which is why I used the other two).

If the computer is clean,

Then sun the system file check.....
START
RUN
sfc /scannow
