I recently bought a new case so I swapped all my parts over into the new case turn it on and I get "hard disc not found!" the sata cable was plugged in, I used a different sata cable, tried it in every port on the motherboard. So I started thinking maybe my hard drive just went bad, so I went and bought a new hard drive but ***... Same result "hard disc not found!" in the bios sata is set to IDE mode. Note it worked completely fine until I moved all the hardware into the new case.
