Not a Windows issue. Replace the CMOS battery (mainboard).

Usually, it's fixed by replacing the battery.

Yes. You need to replace the CMOS battery on your motherboard. It's normally
a little metal disk about the size of a quarter. They cost only a few
dollars.

When you remove it, you will probably lose all your BIOS settings, so it's
prudent to go into the BIOS setup program first, and write down all the
settings, so you can restore them manually if need be.

You can replace the battery without powering down the computer. Then you
won't lose the CMOS settings.

You can also electrocute yourself, fry the motherboard, or both, dong that.
Opening any electronic device with the power on, and sticking your hands
into it is foolhardy.
 
If he is getting a bad checksum error, he has likely already lost some
settings. He is also likely back at the bios defaults, and doesn't even know
it. Well, his computer may be running like c**p

Remove the cmos battery. Turn on the PC. Clear the cmos in the bios setup.
Reboot twice without turning off the PC. If the message is still occuring,
its the physical memory making up your cmos causing the problem. The cmos
battery is only used for saving cmos memory state when the PC is physically
off.

Not all PCs have a removable bios chip. Some have two doing the same thing,
one is a backup.

In rare cases, the bios cannot configure the hardware properly. More common
among systems loaded out, some hardware vying for a hardware irq of its own.

Nah. The maximum voltage on the motherboard is 12 volts, no more than some
flashlights. And I never said use your "hands" (although I often stick my
hands in an electrical device without powering it down -- the refrigerator
being one example). You can use a tool. Like any available intern.

Could be. I've seen that happen, but I've also seen it not happen.

If you use a tool (and it has an insulated handle) you *may* protect
yourself, *if* you are sufficently careful. But mistakes can happen, and
it's foolhardy to take the risk.

And using a tool makes it *more* likely that you will fry the motherboard,
if the tool slips and shorts together two things thaat should connect.

I repeat, doing this with the power on is foolhardy. And it's entirely
unnecessary.

Sorry, that was supposed to be "should *not* connect."
