bitcoin wallet - on a new computer?

[graphicsdump]

My main computer used for my wallet recently suffered a major issue when a power outage has rendered it unusable. It's probably motherboard and/or power supply. In the meantime, is there a way to get my wallet working on another machine? I installed bitcoin-qt and it's synchronizing with the network but it's probably not going to be the same address.

I have my bitcoin address and my passphrase. Any help is much appreciated.

I'm assuming your running windows right?

Anyway, after you've finished syncing the blockchain you can copy your wallet.dat over to your new machine and replace the one Qt generated on your new machine. If you've somehow used the new wallet for spending/transactions then you'll need to backup the private keys and reimport them later.

You can find you wallet.dat on your old machine here:

Code:

C:\Users\YourUserName\Appdata\Roaming\Bitcoin

Windows, yes. My other computer is an iMac. I thought about copying that file over to the folder on my Mac...you think it would work?

Probably. But back it up no matter what.  Wallet.dat has your keys.

Ok, taking a crazy amount of time to sync...I'll give it a go once it's done. Thanks everyone!

Turn on bitcoin on both pcs while connected to the same network.  On the new pc add a connect=123.13.123.123 to the config or command line of bitcoin where you replace the ip with the lan ip of the old pc.

Sync will go much quicker as the nodes will talk to each other rather than over the internet.  

Once it's done you can remove bitcoin form the old machine.  Also remove the connect line from the new machine's config.

Download a linux live cd and bootup your old pc with a USB flash disk, copy your wallet.dat on to the flash disk and hopefully you can recovery your wallet.

I didn't heard about this. Will this faster the syncing process(via localhost)? Should I replace the IP or add it to config?

If you have multiple pcs running bitcoin core on the same LAN you can make sure that they sure they sync to each other using connect or add.  Otherwise you might have multiple pcs downloading the blockchain from the internet.

See qoute below:

Right now there isn't a port number setting to do that.  It's a feature yet to be implemented.  You can only set up your NAT to port-forward to one of the computers.  (I said something earlier about NAT port translation, but that wouldn't work, other nodes wouldn't know to connect to that port)

If you want, as a small optimization, you could run the rest of your computers as:
bitcoin -connect=<the IP of the first computer>

so they get all their network communication from the first computer and don't all connect over the net individually for the same information.  This saves bandwidth, although it doesn't use much bandwidth to begin with, so it wouldn't really matter unless you had tons of computers.

For redundancy in case the first computer goes down, you could have two that connect out and the rest connect to both of them.  The first two are run normally, the rest are run like:
bitcoin -connect=<IP1> -connect=<IP2>

Hmmm quite ingenious doing that, didn't think of it.. Thanks
Dunno if OP can do it if the m/b died on the other computer, but its a trick I will keep in mind when my new laptop arrives any day.

Try importing the wallet.dat files. If you cannot access your disk using windows, access the filesystem using a linux livecd. (do not install it to the computer, just boot), then copy the files. Import in a bitcoin client, and quickly export the private keys.
