Hello Dentelle, and welcome to Seven Forums.

Just to clarify, the restore points would have already needed to been created before you will be able to restore back to a week ago. Increasing the disk space will just allow you to be able to store more newly created restore points.

Double check to make sure that your Windows Event Log service is enabled, started, and set to Automatic. Afterwards, try again.
