I ghosted a windows 7 pro x86 Optiplex 390 and now the dang start button doesn't work. It recognizes when you hover over it but when you click...nothing. I ran sfc /scannow and it finds errors but it says it cant repair them (same thing in safe mode). Other than this one issue, the computer is working flawlessly. I've googled the crap out of this problem with no avail. I've run a chkdsk /f /r same results, does anyone have any idea why this might happen?
