I had a similar issue with my riocar that was purchased in January. Mine would freeze during operation and had slow boot time. Later it started "clicking" during operation (usually prior to freezing) I had to send mine back to the UK for repair from a "dry ide header" as they told me. Hopefully that's not your problem. Also email tech support as they have mentioned to me about a bad batch of ide cables... maybe that's your hangup.
