Disk Check Won't Run

I'm having trouble getting the disk check tool to run on a laptop with Windows 7 Home Premium 64 bit. Whenever I schedule a disk check and restart the computer, absolutely nothing happens -- my system simply boots up as it normally does.

I ran the system file checker when I first encountered the problem; it told me that it couldn't fix all issues, and upon checking the log there is a problem with the autochk.exe system file. I found this Microsoft hotfix and tried to install it, but received a message that said "This update does not apply to your computer." I can't run a system restore to fix the problem because it's been over a year since I last checked the disk successfully, so the restore point that I need is almost certainly long gone. I also cannot perform a system repair because my computer manufacturer did not ship a Windows 7 installation CD with the laptop. I can revert my computer to it's original factory state, but as far as I know I can't simply repair system files, and I do not have a Windows 7 disk from which extract a new autochk.exe file.

Any suggestions would be greatly appreciated. Thank you.

Thanks for the suggestion Brink, but it unfortunately did not resolve the issue.

Hi, Kaktussoft. After running the System Update Readiness Tool, restarting the computer, and running the SFC, there were indeed still errors.

This is the CheckSUR log after the scan:

Also, I find the following string when I look in the CBS log and search for the phrase "cannot repair":

2013-10-15 13:48:47, Info CSI 00000049 [SR] Cannot repair member file [l:22{11}]"autochk.exe" of Microsoft-Windows-Autochk, Version = 6.1.7601.17514, pA = PROCESSOR_ARCHITECTURE_AMD64 (9), Culture neutral, VersionScope = 1 nonSxS, PublicKeyToken = {l:8 b:31bf3856ad364e35}, Type neutral, TypeName neutral, PublicKey neutral in the store, hash mismatch

Yes, that is the only error in the CBS log as far as I can tell.

For the folder that you asked about in C:\Windows\winsxs, autochk.exe is there. The "created" date is 9 March 2011, the "modified" date is 20 November 2010, and the file size is 760 KB.

For the folder in C:\Windows\system32, autochk.exe is again there with the same size and dates as the previous one.

Whenever I try to schedule a disk check, either by typing it into the command line or right-clicking on the C: drive --> Properties --> Tools, it will not run. It doesn't start to run and then hang, it simply does not run at all. My system boots up exactly as it normally does, without notifying me that a disk check has been scheduled or displaying a countdown timer.
