Registry Messed up . Display won't show

So basically the other day i was trying to improve my ping for gaming by using youtube and changing settings in there registry , after i had made the changes no effect had been taking so i attempted to revert what i had done . Instead i have clicked the back up file of the registry i had exported and added it into my registry thinking it would replace , instead it had been added or duplicated into my registry . As i had been warned , but being unfocused and reckless i had pressed ok . After i attempted to restart my laptop the display would not work . My laptop would turn on and the power button would be on and after the Asus start up message " Persistance , Perfection , Innovation , blah blah " the display would go from black to a lighter shade of black and keep flashing . IT doesn't make it to the welcome screen , i can see my cursor for 5 seconds on one of the shades until it flashes back and forth . Idk what to do , should i send it to repairing or does anyone know something that might fix this here.

You can try system restore to the earlier date prior to the changes made in the registry.

Win+X->Control panel->Recovery->Open System restore

nothing will come up on my screen and i had already sent my laptop for repairing
