Q: OSX doesn’t restart 3 days after upgrade to Mavericks

If it is successful try booting normally.
If it only boots into Safe Mode, you have some third-party system modification causing your problems.

How? In Safe Mode or Normal?
You can also try booting into Recovery and repair the disk using Disk Utility: OS X: About OS X Recovery
I'm not sure if this will be helpful in this situation, but Resetting NVRAM sometimes helps startup problems: About NVRAM and PRAM
This contains much of what I've already suggested, but there is a bit more if those don't fix it: Resolve startup issues and perform disk maintenance with Disk Utility and fsck

There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
