First of all I would like to say hi to everyone 
As the title of this post says, My C Drive is corrupted in my Acer Aspire V3-772G. The Last thing I did was I downloaded and Installed some software applications from Acer and all of a sudden my laptop froze and I had to force shut down using the power button and when I turned on the laptop it does not boot but instead it goes into Windows Automatic Repair and after about five minutes it fails and I get the following message:
Automatic Repair
Automatic Repair couldn't repair your PC
Press "Advanced Options" to try other options to repair your PC or "Shut down" to turn off your PC.

I tried everything in my knowledge to reset, refresh or repair the windows installation but with no success.
Below are the software applications that I downloaded and Installed from Acer.
1. Device Fast-Lane
2. LaunchManager
3. Live Updater
4. ePower
This is the download location URL: http://us.acer.com/ac/en/US/content/drivers

Finally I thought of checking the status of the hard drive with "DISKPART" through command prompt and then I found that the file system of my C Drive is "RAW" but the recovery partition seems to be okay. As you can see in the Screenshot below:

I am failry new to Windows 8 and I did not create a Acer Factory Recovery USB Drive because I did not have a 16/32 GB USB Drive, Finally I would be realy grateful if someone could help me solve my problem.
Thanks in Advance,
