Hello! Yesterday my friend turned off her pc after playing overwatch then once i tried turning it on it gave me a message

"no os detected, please disconect any harddrives without an ooerating system" or something very similar to it

So, thats exacly what i did i diaconected the hdd that is used for steam and then it gave me a no post.

I tought that maybe i could enter thr bios and see if it was a boit order issue or a setting being changed just to find out that i could nit even access the bios.

I tried using a usb with windows on it to acess the bios to no avail.
The bios seems dead. I get no info of the model of the mother board or cpu.

I tried running the pc on bare minimum. Being

Cpu ram ssd.

Im not sure if the motherboard just died on us or if its anything else.
When it boots all fans spin everything powers but i get no post.

Any ideas?

EDIT:

I tried booting through a USB but it is only detected if absolutely no harddrives are conected.
i have tried multiple harddrives. I am suspceting the motherboard might be faulty?
