Just wanted to say thanks for this. Both BitPay and Coinbase don't seem to understand that not having the items in the cart passed through to the invoice is not ok. You did very well, and I appreciate it.

Sent 0.00642btc your way too. :-)

You didn't mention what brand you are using, or where you live. Some areas of the world have dodgy power with lots of brownouts, but usually it's a crappy PSU. You are using well under the recommended 80% of the PSU, so it is either the PSU, or the power going to it.

I would replace it and see what happens.
