The settings on my PC clock are lost as soon as I turn the PC off. It started like this each time I moved the machine I had to reset the clock in BIOS at start up. Now it never stays on time even after I reset time and date in BIOS, it's off by several hours when I turn my machine on in the morning . I don't know what's wrong and I really need to have an accurate clock. I would appreciate your help.
