This error is on a Lenovo G560 Win 7 Home Premium. The system runs for 1 minute and the announcement comes in one minute after the warning it shuts down and reboots. It happens in safe mode and normal. I have attempted to disable the automatic restart on system failure but it didn't do anything. The system has Microsoft Security Essentials working but it is not able to complete a scan before the computer reboots. It's very difficult to do much diagnosis with only 2 minutes of up time before it reboots. I've tried to take if off the internet and that has no effect. Your help would be appreciated. Thank you.
