"CMOS Checksum Error"
Posted 07 May 2005 - 03:20 PM
I went to turn it on, pressed the power button, nothing happened. Pressed it again, it booted up. As it ran through the DOS startup, before it got to Primary Master, it stopped and said "CMOS Checksum Error- loading defaults". I pressed F1 to continue and it loaded into Windows fine. Unfortunately, it had reset my date and time as well as my CPU settings. My CPU is a 600 Mhz PIII, but it turned it down to a 200 for some reason. I fixed everything and rebooted it, and it was fine, but now, today, I went to turn it on again and the exact same thing happened. What's going on? Why is it resetting everytime I turn it off?
Help is greatly appreciated.
Windows 98 SE
600 Mhz PIII
128 MB RAM
GeForce 4 Ti 4200
Asus Mobo (not sure of the model number)

One way you can confirm it's the battery. Restart and go into the BIOS setup and make some simple changes that won't hurt you or the system any. Save the changes and let it restart and boot like normal. Shut down the system for about 10-15minutes. Then bring it back up and see if you get the same error.
A new CMOS battery is only a $2-4US.
Shut down the system, pop out the battery and take it down to RadioShack they should have one perfect for you.
