My Powerlogix 1.4ghz needs to go back for a second time as it still locks up regularly. Powerlogix has apparently isolated the problem by testing several Cubes, but I am still awaiting my RMA details. I understand the newer 1.35ghz versions aren't affected. Allan, you most likely have a bad upgrade - especially if everything is fine with your old processor. I replaced the system and tried three different hard drives but it was the 1.4ghz upgrade that was conflicting with something. Sad as going back to 450mhz seems way too slow now! Bryce.
