I have just built an SBS 2008 server on an Acer Altos G330 MK2. Plugged in a Maxtor One Touch4 Plus by USB for backups. The server has started locking up on reboot and occasionally locking up for no know reason.
I have determined that without the Maxtor plugged in the system boots normally. Still testing to see if it is responsible for system locks.
The system hangs prior to the acer startup screen. The one that says hit F2 or F10.
