Hi Nisko,
can you post a copy of the logs please. To be honest if your machine is running fine then i wouldn't worry too much about it. Often these 'corrupt' files can relate to items which won't hurt the os and if you upload the logs we can have a quick look for you..
I doubt Repair would be the solution although you could try going back using system restore or boot into the advanced boot options (where you find safe mode) and click 'Last good known configuration'.
Lastly try a clean install, change the boot order so you boot from the actual install disk and perform a clean install.
