ProI have a problem with AereoBook

I have a problem with AereoBook
It always went without any problem now when I turn it on …from a black screen, the back lighting of the keyboard goes.
I tried attaching it to external monitor but nothing.
After several attempts by holding F2 and F3 it goes to the Windows main screen but the screen every 2 seconds disappears and then the Pc shuts down.
Basically there seems to be problem with video causing pc reboot.
I don’t know how to do it because it won’t even enter my bios.
How can I fix it?
Thanks
