Unity crash on Any Project opened

Hello, till yesterday everything was fine at v5.3.3f1. Today tried to open the project I was working on yesterday but immediately after opening the project there is a Unity Bug Reporter. Tried opening another project but the problem still exists. Deleted Unity and reinstalled same version but still same error. Upgraded to v5.3.4f1and the problem still here.
No idea what is the problem and what to do.
Any ideas ?

EDIT : Same goes to Creating a new Project

Ok so found my problem . But have no idea why. Having a dual monitor setup. As soon as I disabled the 2nd monitor Unity started without problem. The thing is that till yesterday it worked fine so why today? And basically why at all ? Should I be worried about my VGA ?
