I thought timekeeping was about the most basic thing a computer can do. Apparently mine doesn't know how. For the past three days my Win XP box has been unable to keep accurate time for more than 5-10 minutes. I synched it at 10AM, it showed the right time, 4 minutes later it said 11:30AM. Sometimes it seems to just "run fast" as well.
I had this problem on a Windows system a couple years back, and it turned out that a video game I played (Stronghold), used the system clock to give you a different greeting when you started the game, i.e. Merry Christmas, Happy Halloween, etc, and it messed up the clock.
So, possibly it's a software issue, especially it you have something that's using the system clock a lot?
Aaron, my clock was off, thanks for the tip. Unfortunately the reboot brought up another recurring problem I have with this board (Asus A7N8X Deluxe that everyone raves about... an amazing board for features and overclockability otherwise)... it decided not to power my USB keyboard or mouse.
I wonder what genius wrote the "Keyboard error or keyboard not found. Press F1 to continue." error.
Searched my junk box and got a USB to PS2 adapter out again to fix things up.
