Reformat and reload the OS.

That fixes everything OS related.

I format and reload my OSs every 6 months at the max.

That doesn't work if your HD is dying, and they do die. Also motherboards die, and so do power supplies.

And if you feel you have to reformat and reload your OS every 6 mos., something ain't right. There is no reason for anyone to have to do that.
