Hi everyone.

I recently smelt something burning on my pc, it shut off, and now when it comes up it gives me an error message saying "Checking media presence...no media presence detected." I took it to a repair place and was told that it's not the hard drive or M.2 (though I'm not ruling them out. I don't know how well they checked either of those) and that it's probably the motherboard. I'm not convinced that it is the motherboard, so I wanted to see if I have any other testing options before trying a new motherboard.

The warranty is expired.

Things I've tried:

Manually setting the BioS in Bios bootup, it can't detect a drive to boot from.

Dell hardware diagnostic. It says everything is running how it's supposed to be.

Specs:

4.6 GHz core_i7

16 GB DDR4

2 TB Hybrid Drive

GeForce GTX 1080

Windows 10
