Start Up Error

[Guest]

Hi
When I switch on my computer I receive an error message and have to press F1
before it will startup. There does not appear to be any problem once it does
start up. The message is as follows:
Warning CPU has been changed or CPU ratio changed fail please re enter CPU
settings in the CMOS setup and remember to save before quit.
Has anyone got any idea why it is doing this and what I need to do to
resolve this problem.
Thanks

This has nothing to do with Windows, this is related to your BIOS.

Try replacing the CMOS battery first. The problem could also be any number
of hardware problems.

When was the last time you thought about the battery in your PC?

Also you may need to read your computer manual.

BIOS is an acronym for basic input/output system.

CMOS is the physical computer chip that holds the BIOS settings in memory.

The CMOS or Complementary Metal Oxide Semiconductor is an on-board
semiconductor chip. Which requires very low power generated from various
types of CMOS batteries. This chip is used to store important system
information and configuration settings while the computer is off and on.
This also allows things such as your time and date to be stored on your
computer. This important system information is the BIOS info.

The BIOS settings that you use to control how your PC works must be saved in
non-volatile memory so that they are preserved even when the machine is off.
This is as opposed to regular system memory, which is cleared each time you
turn off the PC. A special type of memory is used to store this
information, called CMOS memory, and a very small battery is used to trickle
a small charge to it to make sure that the data it holds is always
preserved. These memories are very small, typically 64 bytes, and the
batteries that they use typically last for years.

Thanks for that Wesly and I have read your links, however the computer is
just over a year old so would this apply to it already ?

Sarah,

I have no concrete idea. How old was the battery when the factory installed
it? Who knows.

Batteries are around 3 bucks. Replace the battery, then you'll eliminate
that as a problem.
