CMOS checksum error; all folders read-only

by ayhage / November 12, 2013 1:19 AM PST

Recently, I have been getting the following message on booting: CMOS checksum error; and then I found out all my folders had become read-only, and I couldn't change their properties. What could it be?
I have run AVG which did not detect anything.
My desktop (xpc) is running XP SP3

Clarification Request
Good questions but

The cmos checksum error is well done. Did you try replacing the old battery and setting the BIOS settings then saving them? (sorry but that topic is rather well done.)

The all folders read only could be related but until the checksum issue is fixed I would NEVER work on the hard drive except to back it all up again.

try removing the cmos battery for 30 minutes then putting it back in, you might need to reinstall your o.s. to fix the files
