    Default Is My MoBo Dead? Lightning Strike Took Some Components........

    I had a storm and lost my garage door sensors, an on-board NIC on my other PC but it had two :-).

    So on my GA-EP35-DS3R it lost the power supply. I replaced it and she loop boots not detecting any hard drives. I get a singlr beep and the looping boot.

    I reloaded fail safe BIOS.
    I swapped the SATA ports.
    I put in a HDD off the shelf. They spin up but are not detected.

    No Go! Now what? How do I tell what to do next before trashing the MoBo?

    And yes, a better power surge is coming but it was a nuclear strike. A massive boom that I'll not forget.

    Try clearing CMOS, a few hours if 20 minutes don't fix it.
    But if PSU was damaged very possible other components were too.

    Well naturally I had to clear the CMOS for a few minutes cause I couldn't wait and things did change.

    It seen my HDD's now and gave me the choice screen of last good known or the other choices that come with clearing CMOS. I chose "Default". I tried the last good known too.
    So when I had changed my SATA ports during trouble shooting I never put them back. I did this to port 0 and port 1. I have 2 HDD's in the machine.
    Then booted and it seen one of them in two places. Port 0 and port 4.

    So I am going to bed and gonna clear CMOS tomorrow for as long as you recommended and start again.

    Anything else?

    thanks

    Leave CMOS battery out for the night and a jumper on CLR_CMOS pins too.
    All that while the PSU is turned off of disconnected.
    Gave you tested the drives themselves in another machine?

    You may want to look into an Uninterruptable Power Supply (aka UPS). That -should- protect you even against lightning strikes more or less (lightning hitting the computer, not so sure :)). This should be standard equipment for anyone who leaves their computer on 24/7 and/or unattended. Fully worth the price and the bigger the better--well, the more stuff you can hook up to it.

    Standard "surge protectors" are typically inferior because damage can happen before the protective circuit is broken. UPSs work differently.

    Follow directsion from 2nd half of the 2nd post on how to clear cmos. http://forums.tweaktown.com/gigabyte...ash-guide.html After clearing renter bios and chose Load Optimized Defaults. Press F10 key and save and exit. Renter bios and make changes to memory and HDD (as far as raid or ahci mode) Press F10 save and reboot.

    There really is no physical need to remove the battery over night. simply shorting the clear CMOS pins will have exactly the same effect. Shorting the pins or removing the battery over night is an old wife's tale, as useful as trying to avoid the cracks in the pavement. If CMOS could truely store charge for that long without a power suply then it'd be a scientific marvel. Forget any so called "evidence" saying that anything like this has ever been of benefit because it's anecdotal at best.

    Do as acebmxer says, clear the CMOS once, load optimized defaults, save and exit then see how it goes at boot. There may be a small chance that the EEPROM the BIOS is stored on has been corrupted in some way. If there is no physical damage then a BIOS flash should fix that.

    Well, She will not stop looping. I did all the suggested above including a bios flash, HDD and RAM swapping she will not take. I get a single beep and she loops. Anything else?
    I cannot find a GA-EP35-DS3R anywhere. I would like a GA-EP45-UD3P too. I REALLY would like to save this pup.
