Bitcoin Forum

So, i swapped out my motherboard for a newer one. Rest of the setup stayed the same. I restart the machine, windows xp boots up, discovers the hardware, reconfigures, all is good. I start up bitcoin....all my coins are gone. Why did this happen?

Helen Feiss? :)

Tell me how you turn off the computer before replacing?

Not sure how this is even possible to happen - but, if you had made a backup, you wouldn't have that problem now ;P

I'm not sure how this is possible either. i am stunned. it was only a few hundred btc so not too bad, but still...

I shut down bitcoin client, shut down windows, all good and proper. Bizarre...

*Only* a few hundred?  It's going to take me YEARS to get a few hundred (and I probly never will)...   ;D

Don't know why this might help...but have you tried to see if the bitcoins show up again using the old mobo?

I'm lucky enough to not have to tinker with windows anymore, but assuming hardware is functioning correctly my first actions would be to check if windows didn't switch users or something. Do a full disk search for files called wallet.dat as you might find more than one :)

so simple? i tried to run WinXP after replacement of my old ASUS mb for a new one (ASUS) and there was so many errors with drivers that i decided to reinstall XP... / use search for "wallet.dat" if nothing else was lost you should find your wallet

Ok...so false alarm. Sorry to create forum spam.

The motherboard i switched to had screwed up time on it. I believe the effects of this are documented. NTP never updated until i set the time reasonably close to actual. I simply didn't notice it. So, it rejected all the blocks i created because they were from the future and wasn't taking any new blocks in from the network. I only noticed this because i was doing some calculations with block count and realized it hasn't changed.

Thanks for letting us know, instead of just disappearing. Your post will no doubt help someone else who finds themselves in a similar situation.
