So I upgraded my gpu to an rx 470 and both of my hard discs are gone???? I can't find them in the file explorer. I've got folders from there saved on my desktop and when I open it it's just in some quick access section, not my hard disc. I recently installed an SSD and another hard disc so overall ive got 1 SSD and 3 hard discs or hard drives? Don't know what to call 'em. the E and F were originally my C and D drives I believe, but after installing the SSD and such and moving around everything they changed to that.I'm really freaking out since all of my projects are in there how can installing a gpu cause all of this??
