Suddenly powerloss results in no booting anymore

Posted on 2012-08-16

For a strange reason the power suddenly drops and all my computers are off.
So called an technician and the main fuse was blown. He repaired it and everything works fine, BUT my main computer doesn't boot anymore.

The screens hangs on this:
Screen on startup
So i removed some memory banks and tried again, no luck.
Then i disconnected all the harddrives and dvd drives, still no luck.

Suddenly i see that my CPU fan is not turning and it even by hand it is hard to turn, so probably it's been broken for a while. But my CPU has 2 fans. On on the top and one on the side.

So i replaced the fan by a new one, but offcourse this doesn't solve the problem either.
Then i replaced the power supply and connected the nessecary devices, still no luck.
Then i removed one of my 2 videocards, but again no luck, i changed one for the other videocard and even that doesn't solve the problem.

I can enter the BIOS and change settings, so i set the default profile, but that doesn't help either.

Anyone an idea what could cause this problem?

Besides this, i can't even access my data on my striped raid setup by booting from CD, because it hangs on this screen. So if you could tell me how to recover the data from these drivers, that would also be helpfull.

Motherboard: Gigabyte x48-dq6
CPU: Socket 775 Core 2 Quad 2,66 Ghz
Memory: 8 GB

    Your computer is unable to find any drives.  CDROM, Hard Drive, etc.  I'm surprised it doesn't say "No boot device found." and hang there.  

    Try reseatting the hard drive cables and the CD/DVD cables.  You may have a bad motherboard.

    Additional note: The 9 leds wich indicate the load of the processor on the mainbaord are all burning. So indicating the processor load is 100%, wich shouldn't i think while hanging on this screen.

    Then it should at least say no operating system found.
    But when i enable my RAID setup again in the bios and connect my 2 drivers with power, it is detected by the RAID BIOS, but still hanging on the same screen.

    With striped raid, do you by any chance mean RAID 0, and is that where your OS was installed on?

    If it was RAID 0, you have lost your OS and data. You'll have to reinstall the system or restore it from backups. Power failures are almost 100% certain to kill a RAID 0 array, and as RAID 0 has no redundancy that means you have lost everything. I would never put the OS or any data onto RAID 0.

    My raid array is still good and nothing wrong with it, but just to proof my point, even with a new sata disk connected alone and trying to boot from a windows 7 CD, still hangs on the same screen.

    This is not a disk issue.

    Accepted Solution

    Based on the screenshot provided it looks like its hanging at the point it talks to the IDE/SATA controller to boot...

    Have you tried disabling all the RAID/SATA onboard controllers, enable just the CD drive(whether its SATA/IDE) and try to boot with just the CD?

    Want to see if its possibly an issue with the controller, which if it is means probably new board...

    Actually I missed something...that screenshot doesn't even show any drives(CD nor HD) - so next thing is the controller is probably failed which I've never seen before, but would explain why nothing else appears on the screen at that point...

    You say in the BIOS it shows the drives ok? CD drives as well?

    Just for the heck of it can you reset the CMOS by moving the jumper on the mother (usually labeled CLR CMOS).  Then boot into BIOS and load BIOS defaults and then try booting without your RAID attached.

    i suggest to use the minimum setup to check if you get a complete post
    it looks like a device is blocking the post, so disconnect all cards, disk and cd drives, leave only 1 ram stick etc... as described in my article here :                  (Short-overview-of-how-to-troubleshoot-bad-hardware-when-a-pc-does-not-post)

    if it still does not complete post - and you have reset the bios - it probably is a bad motherboard

    I stopped frustrated last night with troubleshooting.
    This morning i moved my computer to my test area and quess what, it boots again......

    So placed the original hardware back and booted again and it still works.

    Probably some component was to hot and after a night off it could boot again.
    Only thing i could think off is the CPU.

    Anyway problem solved. Thanks for the input.
