Constant Crashing Unity 5.x+

Since I've upgraded to Unity 5 I've had nothing but issues, constantly crashing and even if I go back down to to 4.x it now crashes constantly and my searches and attempts to fix it have come up blank and now Unity has been made impossible to work with right as my product is nearing completion for release.

I've tried to create blank project and simply press play and the same thing occurs, not responding.

I've also tried reporting the issue with my log and such and I got nowhere so I checked my hardware and OS out and all check out fine so I don't know what to do, I want to complete my project but it seems like I'm going to have to jump ship to another engine as I am unable to find a fix.

This is my last effort to get this fixed and corrected so if anyone has any advice or could help me I would be eternally grateful.

Thank you.
