I have a problem that perhaps others have as well: my computer clock keeps getting slower and slower. Is there an on-line clock service my computer can occasionaly access and re-align itself to the true time? ---

if your computer clock keeps getting slower and slower, there’s a good chance that your CMOS battery is weak. Get a new battery. Otherwise, there is software to align your computer clock. if **Nada** ’s link doesn’t help, let me know and i’ll post another… ---

Uh, I’m looking on the back and underneath my computer for the access panel for this battery…do I have to pull off the entire housing of my tower? Its an etower 333k. ---

Yes you will have to take the cover off. The battery is on your motherboard. It should be silver and about the size of a quarter. ---

Try [http://www.analogx.com/contents/download/network/ats.htm](http://www.analogx.com/contents/download/network/ats.htm) . It is a program that will automatically set your clock according to NIST. While you are there, try out some of his other programs. He likes writing software that is small and efficient. ---

I like the Beatnik Internet Clock at [http://www.somedec.com/](http://www.somedec.com/) Just a guess; are you using a P2P file sharing client? I found that several of these will slow my clock down.
