No Check Disk is run because your partition is probably NTFS which means it's a journaled file system which in turn means that all operations to the disk are first logged and then executed, and when they are successful they are then eliminated from the journal, so the journal is basically a checklist of disk operations as a safeguard from incomplete writes (computer shutdowns unexpectedly). That said, if you are suspicious of your system partition health, you can always make CHKDSK run at next boot, by running it from the command line (it says it can't run because the drives is being used, but asks you if you want to run it at next boot).
