CMOS time wrong, Pls press F1 to continue!

Each morning when I start my Coumputer it will always ask me to set the CMOS time and this I will do and click on ''save and exit''. I ve changed the CMOS battery twice. I ve updated the computer time with the OS and the internet as well. I have exchanged the memory with another, all in vain. When I start the computer the next day I will always get the above message. Thanx.... Nd

Intel Pentium 111, 600Mhz Cpu on a tatung motherboard, 128MB mem, using XP pro.

Sadly, could be the end to that board.

If a new battery doesn't cure it, then here's how I've fixed this issue.

1. Upgrade the power supply. It floored some owners that an aging power supply may not meet a minimum voltage rise time on a supply leg and could corrupt the CMOS settings or real time clock when it's powered up. This also can be a cold only issue and only by swapping in a 100 more Watt supply and giving it a few days may tell if that's it. Cheap.

2. Replace the motherboard. It is possible that this 5 plus year system has developed a board fault.

RTC componet maybe bad, or the circuit involved is. Also, a bad CMOS battery contacts and/or wiring. What happens after changing the battery, does it remain OK, then fail after a week, etc. Check the bios for any possible "save" feature addressing the clock. Finally, as systems age, they do some starnge things that refuse to be fixed from normal attention. IMHO, strip the system down and clean well, reseat whatever you can, clean *all* contacts and maybe swap the power supply only for good measure. Inspect all contacts, wiring, harness for kinks, cuts, swap if possible and use a FRESH NEW CMOS battery. If the problem still persists, just live with it or replace system or what can be swapped within reason.
