System Restore, Windows Update and ATI's CCC files corrupted

By following the tutorial of how to run System File Checker I found the files malgunmc.ttf, wucltux.dll Amd64\hpd7500t.dll (part of prnhp004.inf) were all corrupted. I ran System File Checker several times to see if it would automatically correct the files…it did not. So I followed the next tutorial “How to Extract Files from the Windows 7 Installation DVD” and extracted the files and replaced them…this did not fix the issues either (ran System File Checker afterword’s and it found same issues). I replaced the files twice, once in normal mode and after it did not work in normal mode tried it in safe mode, no joy. I am at a loss what to try next, I do not want to reinstall the operating system due to the computer is working fine even with these issues, windows update does work automatically I just cannot do it manually. Any idea’s what to try next?

Thanks for the reply Brink. I tried the System Update Readiness Tool and it still shows the same corrupted files after rerunning System File Checker, ran it four times too. I also tried Chkdsk (only checked for errors), anti-malware and anti-virus programs in normal and safe mode...they found no issues. Thanks for the help Brink, any other ideas?

I was afraid you would say that. I think I would just do a clean install. I was trying to avoid having to activate Windows again, might as well do a clean install...it is better in the long run. I have changed hardware and reinstalled so many times now I have to phone it in now with all those numbers...what a pain. This was a clean install a few months ago and I'm not sure what corrupted those files. From the research I have done seems a windows update may have been the cause. Or it could have been my memory settings were wrong. I found a few weeks ago I had my memory set to 1600, but at that speed I should have had the Command Rate at 2T...I had it on 1T. That is like a bad overclock. Thanks for the help Brink.
