Hi I've had this issue for about 3 months off and on, my computer is an Intel i5 on a Asrock Z68 Pro3 Gen3 8 Gig Ram and Nvidia GT740 with 750 watt PSU, I start my computer and it tries to boot from a different hard drive, I've gone into bios and set the drives correctly and it will work for a few days then revert back to trying to boot from one of my other drives. My boot drive is a Corsair Neutron 128 Gig I have plugged it into my Sata3 port on the board, I have also tried it in the Sata 2 port with 1. CD Rom - 2. Neutron SSD - 3. Seagate 1TB - 4. Corsair Force 3 - 5. Corsair Force3. I can't figure out what I'm doing wrong, can anyone help me with this issue please.
