|Motherboard won't load from any attached I/O device. |
After more than a year of uneventful operation, my home-built tower system's motherboard has suddenly stopped loading from any and all attached devices. I run Ubuntu Linux 12.04 LTS OS on my boot HDD, with Windows XP Pro SP3 on a second HDD running (when I use it) as a VM under Oracle's VirtualBox.
The symptom is that when I power up the system, it goes through POST apparently successfully, checks devices and displays the GRUB menu. I select loading Ubuntu 12.04 LTS and after a brief delay the following message displays:
run-init: /sbin/init: I/O error
Kernel panic - not syncing: Attempted to kill init!
Pid: 1, comm: run-init Not tainted 3.2.0-27-generic #43 Ubuntu
followed by 7 lines of trace information. Then the system halts, with the caps lock and scroll lock LEDs on my keyboard flashing in sync. If I select Windows from the GRUB menu instead, the screen about Windows not having started successfully displays. When I select "Start Windows Normally", the Windows splash screen displays briefly, then the system restarts and loops back through POST, ending on the GRUB OS selection menu again.
I've tried a number of things to identify what's going wrong, but none has helped so far -- the result is always the same. They are:
1. Reseat cables; 2. Replace IDE signal cable to first optical drive; 3. Rub possible corrosion from video card and DRAM contacts; 4. Disconnect SATA cables from HDDs and SATA optical drive, singly and in various combinations, re-booting each time and attempting to load Linux LiveCD or Linux rescue CD from either of the optical drives, or Windows from one HDD, or Linux from the other; 5. Change boot device orders in BIOS: 6. Clear CMOS: 7. Reset BIOS to default settings; 8. Disable all but first core in processor.
I'd sure appreciate some help fixing this problem -- I'm about out of ideas.
