I tried to switch beetween integrated and dedicated in bios but nothing.
What can i do?

Did you try pulling the CMOS battery out and waiting five minutes before you plug back in and turn it on
 
Yes. Let it sit for several minutes at least and then put it back in and power it on and see if it comes up
 
Try removing the dedicated GPU and try booting only integrated graphics. You may need to do what’s called Breadboarding the system. If I were you I’d remove everything but the CPU and RAM and hard drive and see if it boots
