I'm having a problem with the cmos. This is the error i get when i turn on my computer "warning! CPU has been changed or CPU ratio changed fail." When i do re-enter the CPU setting in the cmos it does not let me save. The computer just freeze. I clear the cmos but still the same problems.

PLEASE HELP...........

thank you

Are you experiencing any other BIOS anomolies, i.e. are any other settings like the date and time being lost? If so, the evidence would point to a dead or defective motherboard battery. These are easy to replace and cost just a few pounds from any computer shop.

I am experiencing the same problem but with a new motherboard , cpu(Celeron D 2.4GHZ) and ram..... its a panasonic backup battery

its very annoying......
there is no operating system yet, and i don't know what to do.....



Please help me... Thankyou very much!!

Do you still have the old motherboard? If so, try swapping the battery. Although they generally last 5-10 years, I've known dead batteries even on relatively new motherboards.

Also, make sure the 'Clear CMOS' jumper isn't enabled, otherwise it will be wiping your settings each time you come out of the BIOS.

the m'board is one day old....

the battery looks dam new.... -_-
i have also made sure the jumper isnt set to clear CMOS, i think when i got it, it was on 'do not clear' by default.... it should be right?

i also found out what my other problem was, my 2nd HDD was rooted, so i just threw it out...!

everything is AOK except for that error and it needs an Operating System....

Yeah I know but it's best to rule it out just in case. If nothing faulty ever left a factory, you wouldn't get a warranty would you?

Yes, you're right - the jumper should be on 'Do Not Clear' all the time (unless you're deliberately trying to wipe it).

but what does it wipe?? the entire HDD's?? or just settings to boot the computer....

Thankyou so m8uch for your help...!

Is there data on the drive already? Clearing the BIOS may alter (i.e. fix) the way that it reads the drive but it won't physically wipe any of the data off. Clearing the BIOS should just clear all of the options that you see when you go into the BIOS screens and will restore them back to the 'factory default' settings, which are generally the most compatible settings (motherboard manufacturers generally want to make the default settings as reliable as possible so they don't get loads of helpdesk calls).

there is data on them yes - it was a second HDD for my main computer..... (the families)

I stole it and plugged it into mine

gotta love it ----- umm..... it shouldn't make a difference if it hasn't got windows on it?

Nope.
