<human>: Can you give me the gist of the text in a nutshell?

I'm not tech-savvy at all. However, I woke up at about 10:00am today, turned on my computer, went about my business. I grabbed a bite of breakfast, came back to my computer. It was trying to auto-repair itself.

I canceled everything that was happening, turned it off, tried again. My computer (I run Vista) went through the steps until it went to a boot screen. With the options [Start Windows normally] or [Start windows with repair blahblahblah]. I click Star Windows normally and almost immediately, my computer blue screens.

I restart the options and after a few attempts, I eventually get my computer to system restore itself.

I run my Malwarebytes in case it was virus related, nothing. I continue along, browsing Reddit and what not, until just now, when I tried to open up League of Legends. Some problems there, and then with that failing, I open up Starcraft 2. It patches itself (due to the System Restore) and gets to about 70% before it tells me it can't patch due to an error and I might have to reinstall the game.

Now, how do I go about doing this so I can go back to playing my favorite games?
<bot>: I have no idea how to computer and need some helping recovering after a System Restore / bluescreen whammy. I am not a clever man.
