I have been using Intel Celeron 433MHz processor for the past 2 years. Of late, the system clock is running slow. Every time i adjust the clock , after some time ,it goes slow by over 30 minuts to 1hr Does it mean, the processor has problems . Should the processor be replaced/upgraded ? Someone plz give me the reason for this "slowness" of the clock and also suggest me a way out. Thankx in advance.

CMOS battery more likely, and much cheaper, than CPU

Replacing your CMOS Battery General Misc. 1.Boot your PC and enter its setup mode. If you watch your screen closely as it boots, it usually will tell you how to enter your Setup. Often it's pressing F1. 2.Write down all of the settings from the various menus. 3.Power off your PC. 4.Open the case and locate the battery on the motherboard. See your user manual for specifications about the battery and its location. 5.Obtain a replacement battery from a local or online computer parts dealer. 6.Remove the old battery and replace it with the new one. 7.Document the date you replaced the battery.> 8.Replace the case and power on the PC. 9.Enter your PC's setup mode. 10.Reenter the settings you have written down from the various setup menus. Tips: 1.Norton Utilities and similar software suites usually contain utilities that allow you to backup CMOS settings to a floppy. Use such a utility in place of writing down and reentering settings. 2.Don't forget to observe proper anti-static precautions when operating inside the case of your PC. 3.If you can't see your battery right away, try removing expansion cards or unplugging cables. Most newer motherboards use lithium batteries that look like large watch batteries.

3 for 3 ...battery

You guys are probably right. But I've been having the same problem before AND after I changed the battery last week. Every time I reboot, my clock is right. But as I use my computer(which is virus free and has next to nothing running in the background)over the span of about 2 hrs or so, my clock falls behind. I am beginning to suspect my motherboard is going out. Does that sound like it could be it? Rohit, does your clock correct itself when you restart it?

Has anybody had the same experience? Having the clock still run slow after replacing the battery and found out it was because of a motherboard problem? I still am not sure what is causing this after fdisking and rebuilding my system, shutting everything non-essential down in the background and frequently updating and running my Virus protection. I had run a hardware test before also, but will try it again to double check. Could a faulty motherboard be the problem, if all those other things have been done?
