CMOS checksum error problem persists

[Raptor]

I recently installed a new Power Supply Unit. A 420 Watt Dual Fan Chieftec.

However, I have a Trust multiple wall socket with an on/off switch. If I keep it on, but turn my computer off, there will be no CMOS checksum error, but if I turn off the wall socket when my computer is turned off, there is a chance of a CMOS checksum error occuring

What could this indicate? According to this[/url  article it can indicate a faulty or bad BIOS battery. However, the battery is barely less than a year old.

I cannot seem to remove the battery, I once had to reset my BIOS and the battery would only be lifted up a few milimetres. This was enough to make it reset, but I couldn't peel it out.

It concerns a Gigabyte 7N400 Pro mainboard. Revision 1.0

Well, what you're describing is indeed the classic symptom of a bad battery.  You may have bent the battery holder where it's not making good contact.  To remove the battery, it's only necessary to pry the contact up a bit and just push the battery out the open side of the clip.

I will look into doing so, then.

What if the battery decides to fail whilst the computer is turned on?

maybe you need to flash the bios....and may not be the battery?

Both Backup BIOS and main BIOS are F14, which is the latest BIOS version for my mainboard.
