Hello devaster, stop x124 generally refers to Hardware issues. Stop 0x124 - what it means and what to try
Also, please remove Reviversoft, Registry Reviver. I didn't notice that you had an A/V installed. Most of us here at the forums recommend Microsoft Security Essentials. Also might be a good idea to install the free version of Malwarebytes and run a full scan on all user accounts.
If you have any further questions after reading the x124 info, please let us know.
