zero status no finished file?

I have reset this and other projects many times. On this and other BOINC Programs.Defraged the system and Checked the files for errors, to no avail.
My Techie has checked out my PC and said 'there is nothing wrong with WINDOWS 7 and can't find any bugs. All other programs except those that relate to BOINC work perfectly. I have deleted BOINC-all files with REVO and reinstalled it several times - no effect.
HELP!!!
