Re: Alienware M17x R2 Random Daily Reboots and Rare Freezes
I had the same problem and after almost 5 months of troubleshooting Dell finally replaced my machine. I have had the new one for 3 weeks now. So far it has run perfectly other than some strange problem with Windows unloading its WiFi, Bluetooth, and Ethernet drivers on reboot. I also have the TactX mouse but that has not caused any crashes or unprovoked reboots.
Frankly, rather than tear your hair out trying to solve it yourself, you had best get onto Dell support because I don't think there's any fix for this issue.
