Gigabyte motherboard GA-MA790x-D54: DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER
Posted on 2009-04-14
In a nutshell, as of about a week ago, this computer won't boot. I've tried and checked several things, including changing the boot device order to make the CD/DVD drive the first boot device, and and have so far been unable to vary the symptom.
From the latest power on with a bootable diagnostic disk in the CD/DVD drive, the bios will display it's initialization messages, will show a "PCI Devices Listing", will show "Verifying DMI Pool Data", will show "Boot from CD/DVD", then very quickly after that will show "DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER".
This "DISK BOOT FAILURE" message is also produced when the hard drive is the first boot device - and is the original reason for receiving this computer.
I've replaced the two cross fired video cards with a simple PCI video card, booted, the problem persists.
Disconnected both hard drives (one is sata, other is ide) and both (ide) CD/DVD drives, rebooted, and the problem persists.
Connected only the one CD/DVD drive, inserted a bootable diagnostic disk, rebooted, and the problem persists. Also tried OS install disk, same result.
Checked the Bios and it shows that can see the boot hard drive correctly.
Connected the HD sata cable to other sata ports on the motherboard, rebooted, no difference.
Reloaded fail-safe Bios defaults, saved them, rebooted, and the problem persists.
Measured voltage of PSU at the Mainboard connector, the sata power connector at the hard drive, and the molex connector at the CD/DVD drive. All show proper voltage.
My impression is that there is a hardware problem with the motherboard, but hoping that there is something that I may have missed checking or doing that might raise this phoenix from the ashes.
Any guidance or suggestions are very welcome!
