Android : Genymotion could not start

I have problem with Genymotion after re-installing my system.

I have created "Google Nexus 5" machine in genymotion, and it has strange behavior:

• Sometimes it starts normally and works normally


• Sometimes it starts, Android logo is shown (and animating). After that black screen shows and sometimes Genymotion Error shows in a while, somethimes nothing happens


• Sometimes it starts and after a few second, process is killed (I mean windows error "Something happened"


• Sometimes it starts, System is booted normally, but after a second Windows "Something happened" error comes(player.exe).

I have logcat logs from situation n.4 (Starts normally, but player.exe crash).

I have filtered it by Warning+

Could you please help me with that?
