I have an Esprimo Mobile M9400 which suddenly shuts itself down up to 10 times during a normal workday. I have done everything I can to try to fix the problem. I have checked and double checked that I have the latest drivers for every component. I have reinstalled Vista. I have run every diagnostic test available. I have 2 AC Adapters, and the same problem occurs with both. I tought it might have something to do with RAM, since RAM operations in the Vista Index fell to 2,4 (!), but replaced the RAM chips with a new one, and didnt help. Also the fan is constantly running, and sounds like a vacuum cleaner, but the core temerature of the CPU is between 60-65 Celcius. Anyone who has the slightest idea of what can be going on with my system ?
