Crashing after 2nd build

Another crash question, but none of the other topics seem to have the same issue.

So whenever i'm busy with unity, sometimes it decides to crash after 2 ~ 3 sec after pressing play(editor). Even when i wait for 20 min, nothing will happen. After this part, things start to get a bit weird. If i open unity again, the first time i'll press the play button, everything works fine. If i stop it and press it again later, it will just work for 2 ~3 sec en then crash again so i have to reboot unity again. This keeps on happening until i restart my computer, from there it's just a matter of time until the sequence starts all over again.

So in short: when the problem occurs: i can only press play once, after that i have to restart unity. This will continue to happen until i restart my computer.
