Someone is hacking me!?

I've been having a bad day ever since last Friday when the incident of the key logging, hacker showed up to my doorstep and started giving me a lot of problems for me. For Example, the loss of $100+ games that were stolen by the hacker changing my pword and emails, Also, changed three of my emails that were very important, but two were recovered one wasn't. Then, the hacker again try to attack me by changing my keyboard setting on my computer which made all my letters and numbers into one on and which I don't know how to fix it. Also, my firewall picked up his Ip Address and it said he was located somewhere in France. Every minute he is also sending me viruses and keyloggers that my firewall is stopping, but I want it to permanently stop from coming to computer. Someone please tell me what to do any suggestion is accepted.
