BleepingComputer.com: Rundll32 Problems, Amongst Other Things

I've just finished recovering my computer from a crash. Now when I log on I get a message saying:

'Windows host process (Rundll32) has stopped working.
A problem casued the program to stop working correctly. Windows will close the program and notify you if a soultion is available'

I'm not sure why this is appearing but I'd rather it didn't.

I've also run sfc.exe in Command Prompt and it has come back saying that some files were corrupt but could not be fixed.

Can anyone give me a hand?

Thanks in advance,

James
