It wouldn't wake up one day. Was working fine the day before. So I held the power button down until it shut off, turned it back on and it took forever, like 7 hours to boot back up. The screen said it was reparing disk errors. So it is working again but is super slow, really super slow. I'm thinking the hard drive failed as I don't hear it wirring anymore.
Your hard drive is dying a slow death. If you don't know how to work on computers, take it to someone who does. The longer it runs, the less chance you have to save data that is on it. It might be possible to clone it to an SSD, which will speed up your computer.
