The clock keeps losing time. I use a program that sets the clock via the web but it will not hold time very long. It has been going on a long time. Anybody know what could cause this and how to fix it?

If it only loses time during the time the system is powered down, that could be caused by the motherboard battery dying.

The time is all that is slowing down. I do not let it get so far off that the date is wrong. The system is always on so it is not losing time when the power is off.

I've rest the time in the BIOS. Let's see how long it keeps time. I may have to replace the CMOS battery. Thanks for all your help everyone.

Had this situation in a small town back a couple years ago.
Wasn't the computer, it was the power company.
Friend came over and he plugged some meter into the wall. Yep.
I was only getting about 105 VAV and at 59 cycles per second. I telephoned to complain next morning, and was told "How do You know?"
Two day later the transformer up on the pole went Blewey! It was replaced.
Then two days later same friend came over with meter again, and everything was above what was mentioned. Even the televison was brighter.
Stick something into the wall for these things go bad very slowly, and you may not otherwise notice it.

I've had the same situation with my wife's computer. Something was wrong with the motherboard, but I was not sure what exactly. But being a programmer, I've made a workaround. I've added "Block time changes" to my Chameleon Clock - www.softshape.com/cham - so it corrected all the sudden changes caused by BIOS and keeped the time exact synchronizing it with Internet atomic servers.
