I have a mother board with broken BIOS. My time change every time I turn on my computer, even I change the CMOS battery, still won’t save my setting. For able to work on some games and application, I need to update my system date every now and then. My problem is that my computer is installed with deepfreeze. I can’t change the system time. I can’t unfreeze or uninstall the deepfreeze since I’m using it as corrupt/virus protection.
