PC display doesn't work at first boot, but 2nd or 3rd

Hello everybody ! :)

I didn't find a post describing a similar issue, so i decided to make my own.


First of all, i'm not english native, so i've tried to avoid mistakes as hard as i can, but there can be some left :/



So here is my issue:

Recently my PC has some issues after booting up, in fact my screen say " no signal " after the first boot and will work only after 1 or 2 restart.
I don't think the issue come from the boot process, because i can hear the little windows jingle every time.

So it must come from my CG, however i didn't do anything special with it, no overclocking, no recent update of my graphics drivers ( and they are up-to-date, as well as my bios )

More-over when i'm using my PC, it seems perfectly fine, no bug, no error messages.


I tried to un-plug/re-plug the vga after a successful boot and my screen seems to work fine.

Here are my specs :
Mother Board : msi h97m-g43
GPU : Sapphire HD 7850
CPU : i5-4460
Window 10
