: When i turn on my computer it keeps coming up with error messages in dos mode, such as "bios battery low" and fails to boot up. I tried to combat this by going to setup and loading best performance settings and this initially helps, but once windows is running one of my hard drives is not working! I then went to system properties and it told me that the device driver is not working, so when i attempt to install the best one available it says it is already being used. Thyen when i restart my comp the whole process starts over!! HELP!!! It wasnt like this yesterday!!!

It will probably be worse tomorrow and even worse the day after UNLESS you CHANGE the CMOS battery. Find your mainbord manual, you will probably need it. If you don't have one, try to download one from the mainboard maker's web site - for your mainboard model and revision.

Your CMOS battery probably is about the size of a US quarter and easy to spot - most likely CR2032, 3.0V Lithium type; cost <$2 at Kroger, scales up from there. If your battery is soldered in (probably 3.6V NiCad battery) - consult your manual for a stub to connect an external battery. If you can't find the CMOS battery you are in real trouble. The battery may be hidden inside of a Real Time Clock chip - Like Dallas Semiconductor DS12887A or Houston Technology (no longer available) HT12888A or something else entirely.

If DS12887A, you can get a new one for around 20 USD, otherwise you may need to get creative. Please post again if your battery is hidden in a clock chip.

After you replace the CMOS battery start your PC, enter CMOS Setup, select "optimal", "default" or similar canned selection, save and exit. After a few successful reboots you can adjust CMOS settings to your preferred values.

Good Luck,
