Updated CCleaner as usual, ran the cleaning process without adding anything, as usual, now my computer is off. When I attempt to turn it on I get the error: windows>\system32\hal.dll is missing or corrupt and it asks me to re-install a copy. Anyone have any idea how to fix this or what might have caused this? I need the files on this computer, so any way to save the files is needed. Please help, thank you.
