I replaced the hard drive on my HP dv7 laptop and everything worked fine on it until I did an update for avast 8, I believe.  After that I have been unable to boot Windows.  The System Repair is unable to fix anything and the diagnositc and repair details says:  c:\windows\system32\drivers\compbatt.sys is corrupt.   What should I do?

It's possible you have a backup here.




Can you get to a command prompt?


Type the following at the command prompt.

CD C:/Windows/System32/DriverStore/FileRepository/

Then type

dir compbatt*

You should get a long file name with compbatt at the beginning. Do you see it?


If yes, type:

cd compbatt*

Then type:


Is compbatt.sys in the directory?
