Many times hard disk problems can be repaired using the chkdsk command. If you are using windows 7 press the start button in bottom left corner of your screen. If you are using windows 8 / 8.1 press the windows key .Search for "cmd" and Right click it and select "Run as administrator". Windows XP users Click on start > run. In the Run box, type in "cmd" in the box.
Windows 7:

Windows 8 / 8.1

Windows XP


A CMD window should appear. In that window you can just type it as you see "chkdsk c: /f /r". If you have more then one drive or partition, you will need to tell it the disk (chkdsk d: /f /r).
If it is the primary windows disk c: it will ask you to schedule it for next boot. When you restart, it will do a chkdsk for you before even getting to the login screen.

This solution only works for a 64-bit system. It requires replacing files is system32 directory so be careful. Only attempt this solution if you are confident and if other solutions have failed. When Microsoft Visual C++ Redistributable Package is not properly configured it may cause 0xc00007b error. Firstly download the zip file [link] and decompress it. Reboot in safe mode and go to CWindows\System32. copy all files included in the zip package (mfc100.dll, mfc100u.dll, msvcr100.dll, msvcp100.dll and msvcr100_clr0400.dll) to CWindows\System32 replacing the current ones. After that reboot in normal mode.

If all the solutions above haven't worked i would consider backing up data and performing a clean install of windows.
