Bad Checksum on startup

  Andrew-C 12:51 10 Feb 07

Yesterday my computer started to complain that there is a bad checksum on startup. This occurs on the first screen displayed where typically the memory etc. is scanned before startup.

I get the option to check again (always still bad) or to boot with default settings (which works but looses all of my personal settings)

Is there any way to cure this problem and is it a sign of a more serious problem?

If the bios is loosing the time setting when you power down and disconnect the power plug, try a new bios battery.

If the time settings are fine, clear the cmos via the on-board jumper. You may have to check the speed of the cpu and memory settings after you have done this.

If neither work, it could be a defective bios chip. You either live with it, as long as it produces no other problems. Or replace the bios chip ( if it is the removable type ) or replace the motherboard.
