Have you tried running Office Apps in Safe Mode? To do this, hold down the Ctrl key while starting the App. If the App runs correctly, that suggests a faulty Addin is the cause. To find such Addins, check under File|Options|Addins. If you have any 3rd-party Addins, try disabling them all, then re-enabling one at a time and checking whether the problem returns. If so, you've identified the faulty one. If the problem is caused by a faulty Addin, you may need to uninstall it.

A system restore, to a date & time before the problem condition arose, should have been enough to resolve the problems. If you did that but the problems remained, that suggests a hardware fault. Of course, if it's been a while since you previously used the 'Review' tab, the problem may have been there for much longer than you realize.
