Here's the thing, the error can be caused by many different reasons. It can range from the Windows Module Installer having problems (but then again you should be receiving erros on this too) to viruses, or the update itself is really not applicable to your system.
You know what, I want to look closely at the Windows Update logs. Can you follow A Guy's instructions (Ok, I really need some help please
) and do post your CBS file?
We could also help you with your HDD problem. What is the exact error code you get when you boot
the hard disk and it errors? Are you saying when you wake up from sleep/hibernate, your other HDD does not appear but your SSD does?
