hi I would like to ask help on my pc, it just went black on the screen saying select boot device. thought it was a psu issue so I bought and installed a new power supply unit, and still the problem exist, when I follow the on screen instructions saying to hit F2 to run the bios, I saw that even my sata dvdrom is not detected. I bought a sata cable and have it replace as well, yet still same problem. out of curiosity I tried to change the sata ports 1,2,3,4. non of those detecting my hard drive or dvd rom. what other steps or fix should I be doing?
