Hi, I am having an identical problem on 2 different computers. Both using ASUS P4P800-E Deluxe motherboards. The one i'm working with today, October 5th keeps resetting it's date to May 10th. Same problem as mahmuttufanoglu is experiencing. Date is being reversed. Both computers are fairly new builds so I am doubtful it is the battery as well. Has anyone had any luck with this issue?
