I am trying to get Bitcoin up and running on a fairly underpowered laptop and Windows Vista using Bitcoin-Qt After installing and starting the program, I am stuck at at the syncing stage at 92150 blocks and 0%, and have been for several hours. What could I try to get the program working?

  • Try restarting the OS. Commented Feb 12, 2012 at 4:55
  • also try getting the latest release, 0.5.2. can't hurt.

  • I am in the same boat except my wallet is up to date and 7.1.0. Im on ubuntux64 and the wallet wont even start the sync with 8 connections on the BC network. The process is not throwing any errors and the machine I'm on is fully functional. I have cleaned the bitcoin directory twice and rebooted twice as well. I am connected to the Internet as I am still trying to connect as I type this. As of right now after running for several hours, sync is at 0 of 207028 blocks with 8 connections.

Restart OS, restart Bitcoin, try forwarding port 8333 on your router to your machine. If there is no progress after that, you might consider deleting all the files in your Bitcoin data folder except wallet.dat (if you have made any transactions, deleting wallet.dat will make you lose your Bitcoins). If you just want to use Bitcoins casually, or don't want to wait for the client to sync, you can consider using an eWallet.


Bitcoin connects to random nodes by default (home connections too)

To get a fst download you need high bandwidth nodes.

Edit the bitocin.config as described there: What is the fastest possible way to download the blockchain?
