Hello. I have an HP 15-g018dx . When I turn on the computer, the screen lights up but nothing happens. I hit the BIOS key, and it freezes up on the Loading BIOS screen.. I sometimes get "No Boot Devices Found". I took my hard-drive and put it in my other laptop and it wouldn't boot either. Is the computer not booting because hard drive is broken? I switched out the RAM and kept the same hard drive nothing different.
