i built a computer from scratch, but every hard drive i put in it stops working, they don’t respond at all, and i can’t format them either. it starts fine, but it says it can’t find an operating system, and after that, the hard drive no longer works.
can anyone help me figure out what i did wrong? thank you.
P.S: it’s motherboard is out of an hp pavilion. but all the small square connectors came off, so i had put them back on as described on the motherboard.
