I built this computer 1 year ago, and the time Windows 7 time was fine until recently. I figured it was my CMOS battery dying so I replaced it a few days ago. The time was correct for a week or so and now its falling behind again. I made sure the Bios time was correct, but still my Windows 7 time is falling behind. I have tried both enabling synchronizing internet server for the time and disabling it and still no luck. What the heck is going on?
