So my pc stopped booting up after i changed the ram speed settings in the bios (i know its stupid) so i think that killed my cpu. So i then bought a New cpu lga 1155 i5-2400 and i replaced it. But it still gives me 5 beeps while im sure the cpu is not dead as i just bought it. Is it possible that my motherboard is dead? I also reset the bios and i even replaced the cmo battery.
