As I sated I tried to update my windows 7 pc to win 10 but got the error message inaccessible boot device. I tried a second time after erasing my other partition, leaving only my OS. After the second attempt my motherboard reset to its second bios, a previous version which was not compatible with my gpu. I removed my gpu so I could update the bios again, but my pc would start and reset various times before it would even send a signal to the monitor or keyboard. I checked all PSU connections, removed cmos battery, pulled the pc appart cleaned and put it back together but to no result.
I am now using the old mobo and cpu I upgraded from, they both work flawlessly, is there anything I could do to fix my mobo, or is it now a complete loss?

Intel i5 2500
Gigabyte H61M-DS2
2x4gb Ram
CX500M PSU
WD blue HDD

The BIOS probably got corrupted.. first see if resetting it works and use this method to insure it resets correctly:
1. Remove the AC cable
2. Remove the BIOS battery
3. Move the BIOS jumper from pins 1 & 2, to 2 & 3
4. Press and hold the power button for a full minute
5. Leave the BIOS resetting for 10 minutes... if it doesn't work, you may have to do a second reset following the same procedure but extend the 10 minutes to an hour. In case the following suggestion (#6) doesn't work, a third BIOS reset may be necessary with the resetting time extended to overnight. After after this, you can start considering the motherboard may be dead but before giving up I'd suggest trying a different PSU... I know it works with the other...

I know it works with the other motherboard but that's no guarantee it will work with every motherboard, every PC, etc. CX Corsair PSUs (Tier 4) have a bad rep and better to confirm it's not the cause before throwing the motherboard away.

6. After the BIOS reset for an hour, if it fails, try manually forcing the BIOS recovery from the second backup BIOS.. this as you experienced, should and does recover automatically, but not always, and you have to do it manually. You may ask why the BIOS recovered automatically one time and not a second.. but that may explain it, it may be programmed to recover once a set time period, or the settings corruption may not require a second recovery, that's why you should reset it before anything.



Look here for three Manual BIOS Recovery methods after "Clear CMOS"

Thank you, I had to both, reset overnight and force bios recovery but I managed to restore my corrupt bios.
