My A8V deluxe was rock solid stable until I updated to an X2 processor. After upgrading to an X2 the system was practically unusable most of the time. After A LOT of trial and error trying to figure out what was wrong, I found disabling "quiet & cool" in the bios solved the problem for me. The system has been back to it rock solid performance ever sense. Hope this helps. Regards, Jim H
