Windows 7 boot problem

Hi guys, I´m new to this forum so I kinda hope I posted this question into the right section, if not, I´m really sorry.

So here´s my problem;

I have Windows 7 Ultimate 32bit running on my older PC, and everything was just great until I decided to format my pc simply to refresh it.
After I did it, i installed everything + Windows Updates, and then my nightmare´s begun.
After the updates installed, I was rebooting my PC and the updates installed to 30% and the PC simply shutted down, when I was restarting my PC after that, Windows 7 simply won´t boot. I tried system restore to repair it but it was of no success, and Win7 repair setup couldn´t repair it on its own.

So after that, I decided to format my PC again..and I disabled windows updates totally in the ´services´ menu, and it went well for two days! Just 20 mins ago, I was turning on my PC and the same problem occured, i get to the "Microsoft Windows" screen but the logo simply won´t load, it froze. After that I tried the system restore, but this time it worked. Now I´m afraid when I turn my pc off again, that the same problem will occur, so what do you guys think could help me? Because I´m really starting to be frustrated about it :/

Thank you in advance.

perfom a chkdsk form recovery environment
chkdsk/f c:
chkdsk/f d:

Thank you guys, I did both of does things you suggested me.

The bootrec cmds went good without any problems, every operation was successful.

I also did chkdsk, and they were no problem diagnosed, everything seems to be ok.
I´ll keep an eye on it, and I hope that everything´s gonna be good now, if not, I´ll come back and post again!

Thanks for the fast help.
