cmos checksum error - defaults loaded

[tubui]

I just recently put in my CPU and when I boot up my computer it says CMOS checksum error - defaults loaded.

Press F1 to continue. What is this mean and how do I fix it so that it automatically boots up without me pressing F1 and how do I fix the error?

There is nothing wrong with my computer.. I just put in CPU again and put in heat compound and all then I get this message...

:help:

just reset the cmos and you should be set. check ur manual to see how you should do it, there may be a jumper for this or you may need to remove the battery.

I don't think there is anything wrong with the battery. I already tried resetting the cmos but it won't work.

[ripken204]

is everything in ur bios at the default settings? were you overclocked before?

[tubui]

Never overclocked before and I haven't touched my BIOS settings yet ethier.

press DEL get in cmos.....

save and exit.......... that's normal brother....

and deptn what mobo it is .... some ram need to set to by speed... new amd 940 set auto..........

make suire cpu setting is right too.... boot device from cdrom to harddisk ... is your choice.... u need to learn some there to get familiar......

That's usually because of the CMOS getting erased. Just enter the BIOS setup and then choose the option to save and exit.

tubui,

Not understanding how the CMOS or Bios works, you obviously missed the whole point here in this post.....

Just reset the cmos and you should be set. check ur manual to see how you should do it, there may be a jumper for this or you may need to remove the battery.

Some motherboards do not have easily found jumpers to short out the Bios chip and reset it to Factory Defaults. In this case, it's just easier to take out the little 'coin' battery and leave it out for about 20 to 30 minutes to fully Kill the settings in the Bios chip. Then when you restore power by reinstalling the battery, you can set the Bios to your prefered settings,,,,,time, date, boot order, etc. and you're good to go.

The bios will automaticly find the RAM, the CPU and the drives.

Every computer tech in the world has had to do this at least once to solve one problem or another. I've even done it to revive a totally DEAD motherboard. It just WORKS when other methods of recovery have failed.

Even on a fairly new PC, that battery can also be bad. If it checks out on a good quality Digital Voltmeter at anything less than 3.0volts, its bad. Replace it ASAP.

Every PC that's over two years old and comes into my shop, gets a new CMOS battery. Period.

I get them for about a buck, so it's no big deal. I don't even invoice the customer for it.

Weak or dying batteries can cause so many really weird things to happen in a PC, its just not worth leaving a questionable battery in any PC.

Cheers!
