OK so I had built a computer a few months ago and I had to wait to buy another couple pieces (a bigger psu and a graphics card) so I got them and install them no issues there then I turn on the computer download the drivers for the card then go to try and open steam (I hadn't realized the icon was messed up) and it doesn't open (obvs), so I check my computer and my second drive isn't there, I then restart and go into bios, lo and behold it's not there either, so I go about changing all the wires making sure they're all working (my ssd and CD drive show up and work) I then switch Sata ports, using all of them and still nothing, I even bought a new hard drive and that one doesn't show up either, so what could be the issue?
