Please help!!!!!! Wrong date and time every time I switch on my PC!

[myself]

Hi everyone,

I recently got a problem with my PC.
When I switch it on, I get the following message:

" Trend ChipAwayVirus (R) On Guard

CMOS checksum error - Defaults loaded. Warning! A new CPU installed. Press <Del> key to enter BIOS SETUP to set CPU speed.
Press F1 to continue, DEL to enter SETUP ".

Also, the date and time on the PC is never right, it always reverts to 1998.

I don't know why I am getting this message, I have not installed a new CPU. I run an Antivirus software which shows that my PC is virus free. However, I entered the BIOS and set the cpu speed but next time I rebooted the message appeared again.

Could it be the battery in the PC to save the BIOS settings? The reason I say this is because the date and time on the PC always reverts to 1998.

Many thanks for any help.

If your PC is quite old, then yes. I had a similar problem on a machine that hab been running for a while, and it just needed a new battery. The battery keeps the BIOS info saved, and if it doesn't have enough charge, then every time you turn off the PC you lose all the BIOS settings. Try changing the battery as you thought and it should be fine.

Yeah, it's the battery. If you're lucky, you can just switch out the battery. If you're unlucky, you've got a soldered battery, in which case you might as well just scrap the board, since trying to take it out will just ruin the board anyways.
