Let me tell you what I normally do when I start this machine. It has an Intel i7 CPU and as such it uses KMS. - log-on as a normal user. - start X - start a few xterms - start wireless network in one of them - start chrome to log-on onto the LAN of the client - start claws mail - start arora I think that I did not come further as I remember to get a message from my daughter as the last activity of the machine in chrome. The screen went black then and the machine started to reboot. I think that there is not much helpful information I could give. I work since then much longer without any problems.
