Computer Clock Trouble

[XxHeatherxX]

Can anyone tell me why the clock on my computer keeps going wonky? Every now and again it changes the date to like 2003, and the time is never right. It is beginning to affect my Norton Anti-Virus software as everytime the date changes the virus software keeps telling me it's out of date, until I change the clock back to the right time. Why is the clock doing this and can anyone help me sort it out? I've got Windows XP Home Edition.

Any help is greatly appreciated.

your battery may be dying.
you can re-sync the clock each time you start-up.
right-click the time,adjust,internet time,update now

It could be because the battery is on its way out and needs replacing. Easy thing to do in a desktop. :)

You could try setting the time in the bios, and see if that solves the problem.

When booting up, press the delete key, use the arrow keys to navigate. Press F10 to exit. Do NOT be tempted to fiddle with anything else in the bios though, unless you are a sure of what you are doing.
