Hard drive is failing. I really need some help.

[Daichi Ishi]

First, I'd like to say I know little about computers. I don't know exactly what a hard drive is or what's going on. I downloaded Sims 3 from Origin and was installing custom content. There was corrupt custom content, and it wasn't loading into the Sims 3 launcher. Since my whole computer froze and stayed froze, I forced my computer to shut down by holding down the power button. After that, all hell broke loose and I could barely open anything without Microsoft freezing completely. I uninstalled Sims 3 and Origin since I've heard other people have difficulty with custom content in Origin, and got a Sims 3 torrent that I can't even download without my computer freezing. Now, everything is uninstalled, and my computer is still freezing when I open most things.

I also have this photo. It's been popping up now for a good two months. I have no idea what to do. I don't have any money, so any at-home fixes would be great. I'm unsure if the problem is storage or not. I just know it has something to do with drivers.

Hi there Daichi Ishi,

As your system can boot properly, I would say that you really need to back up the data stored on the drive as soon as possible. Most probably the HDD is failing and you will need to replace it.
After you've backed up your data, you can just test it and see what is wrong with it: http://www.tomshardware.co.uk/forum/282651-32-best-diagnostic-testing-utility
