System = Windows 7 64-bit

Various programs, notably Regedit, won't start. Instead I get:

The Application was unable to start correctly (0xc0000142).

Strangly, at least to my thinking, I can launch them via Task Manager.

I am also grappling with AVG errors or over-activity, e.g. reports of Broken digital Signature.

I am also having problems with Excel Update KB978474

I mention these just incase anyone thinks there is a connection, rather than expecting people to solve 3 problems at once.

Thanks for the suggestion. I eventually got SFC / scannow to work in safe mode. It reports corrupted files that it could not repair. Restore points don't go back very far. Is it easy / possible to repair the corrupted files, or should I go for a complete system repair / rebuild? –  Guy Thomas Jun 6 '10 at 9:28
    
whats the exact message SFC is reporting ? SFC is just replacing the modified system files by the originals ones from the CD.(the only way I know to recover corrupted files) you may need to check your hard drive for errors, make sure he's intact. –  Revolter Jun 7 '10 at 1:42
