I disabled a hard disk in BIOS because it was interfering with DVD Drive(I couldn't boot from DVD even if i set DVD Drive for primary in BIOS). Now whenever i want to turn on computer it says: Sec Master : Hitachi HCP725016GLAT80 GMBOA4CA Ultra DMA Mode-5, SMART Capable but Disabled. Computer just stops after that message. if i try to enter BIOS it says : Entering SETUP and nothing happens . I tried reseting bios by removing and replacing jumpers on the motherboard and removing CMOS battery but it didn't work. Since i have 2 hard disks, I disconnected this one and installed Windows 7 from DVD and booted up system normally.I then tried setting BIOS to default but it didn't work. Hard drive is connected to the motherboard as Master via IDE cable.
