Thanks for your help

first thing in your case I would replace the cmos battery.

am i harming my computer by just pressing f1 to continue with the boot?

Nope, it's just that the battery isn't retaining the bios info upon boot, (Boot order, Time of Day, etc. ).. no harm in if it doesn't bother you. :)

what does the battery usually cost and is it easy to install?

[Limey32]

Usually it is easy yes.. like a watch battery. Depends on the motherboard. What kind of computer? And the cost is about $5.

As Limey said, it's easy to install and cheap. You will see it on the motherboard and it looks just like a watch battery. I would just take it to the store and ask if they have it.

most computers use battery type "2035"
There will be a number printed on the battery itself on the + (positive) side. Yeah, between $3 - $5

Sorry, that's battery type 2032 not 2035

oh yes I forgot to tell you what to expect when you do replace the
battery. of course you already have seen it.

you guessed it an error:) why you may ask....
well its simple you removed the power to the cmos but that should be the last
time you see that error and it will get you back up and running but there
may be more to do.
you may have to set some things back that were not load up defaults.
no problems there feel free to ask most on this board have from one time
or another have had to deal with the bios settings.

Hi. Thanks all. Replacing the battery was painless. It loads up fine and I had to re set the date and time. So what in Bios do I have to reset? My computer seems to start up and work fine.



Should there be certain settings? I am using windows xp



Thanks

good to see you got it working.
as for the settings and xp I don't use xp myself but if its running no change
in bios setting is necessary. unless doing so would help fix an issue.

Actually this problem just started. When I logged off my computer would always shutdown automatically. This time it says "it is now safe to turn off your computer". I turn my computer off with the power supply switch in the back but when I turn on my computer again, I get the checksum message again? Is there something in bios that I need to set so my computer turns off automatically?

Thanks for your help

You need to set the correct CPU, memory, and power management parameters. Refer to motherboard manual for details.
