Hey there. So.. i bought a CPU that it really doesnt matter the model and it didnt fit into my motherboard(asus h110M). So i changed back to my old I5 6400 and my GPU(GTX1050) stopped working, when i turn the PC On it turns on as well for 10 sec and it turns off, so my monitor doesnt work. And on top of that my keyboard doesnt work as well, but the PC and the mouse are on.
