I have recently encountered some stability issues after trying to install the following Windows updates:
Win 7 pro 64-bit
KB3057839 (Security update)
KB3068708 (Windows update)
KB2310138 (MSE definition update)
Installation of these updates resulted in several different BSOD errors and boot issues.
During this time I ran the system file checker (sfc), which found violations that it was unable to repair. I also attempted to run chkdsk, which was unable to finish...
