<p>I've tried unsuccessfully 2 times to download the application from this site <a href="https://www.weusecoins.com/en/getting-started" rel="nofollow">https://www.weusecoins.com/en/getting-started</a>. Last failure stopped at around 16,000 blocks. I am trying to get setup with a wallet and begin buying BTC's. I do not want to use an online wallet service.</p>

<p>The only other applications that I had open during the download was Firefox and I use AVG Free Antivirus, but do not know how to disable it. I have restarted the OS.</p>

<p>What to do?</p>

<p>Thank you very much in advance.</p>

Can you clarify the failure you're seeing? Does it just stop, or do you see an error?

You may have more luck if you just use a bootstrap file. [Download one](http://eu2.bitcoincharts.com/blockchain/bootstrap.dat) and put it in your bitcoin data directory (remove everything else from the directory, but let `wallet.dat` stay). Name the file `bootstrap.dat` and then start the client.

The bootstrap file I linked to only contains 190.000 blocks, so after that you still need to download ~40.000 blocks.

Also, as username_5 said, be careful with overclocking. It only takes a single memory error for the chain download to break, and those are far less likely when not overclocking.
