So I had to leave my computer unplugged and powered down for a couple of weeks because I was busy moving and other stuff. When I started my computer up today, I had an error on boot that said something about the CMOS being reset to the default settings. I pressed F1 to continue and it booted fine, except for a few problems. The clock reset itself to December 11, 2001 at 11:54 PM. Second, under DXDIAG, the processor is clocked at 1.1 Ghz when it should be clocked at 1.9 Ghz. Is this a battery problem? Is there any way to test to see if it's the battery without replacing it? I'll replace it if it IS the battery, I just hope my CMOS chip isn't bad.

Replace your CMOS battery, reset date and BIOS settings and relax.

Ok I replaced the battery last night and I'm on the computer now. I had to reset the date again in Windows and it's good now. Except I don't know how to configure the BIOS. It's an Asus A7N8X2.0 with an AMD Athlon XP 2600+ that's running at 1.1 Ghz, not 1.9. I've never configured BIOS settings before aside from making the CD ROM the primary boot device. Is there a guide for this motherboard that explains how to configure it properly?

You don't have to configure it...just the boot settings...sorry, I should have explained.

Long ago (in computer time) BIOS settings had to be written down when changing the battery (or so it was thought). But today, the default settings are invoked automatically when the battery is changed or the CMOS jumper is reset.

The default settings of any BIOS are those which are most likely to boot and probably the ones which came already set on the motherboard/system.

If you reset the time/date and checked your boot order (and saved via F10), you should be good to go :thumbsup:.

It still boots, and I'm using the PC now, but my processor is still running at 1.1 Ghz when it should be running 1.9 Ghz. I'm wondering what has to be done to get it back where it should be?

In the BIOS you will need to set the CPU MULTIPLIER and the front side bus to get your CPU to the correct speed. Not all boards set the multiplier and bus automatically. Post your multiplier and bus speeds and lets see what is happening.

Would that be in the BIOS or can I use that CPUZ Program (I think that's what it is)?

CPUZ will work fine.

OK I got it. Bus speed is 99.5 Mhz and the multiplier speed is X 11.5

You should be running the bus speed at 166mhz. Bump it up and see if everything works OK. You might even get lucky and overclock it a bit.

166 Mhz actually sounds like the right speed for some reason. I think I've seen it before. I don't know how to overclock and if I could, I could only go up to 2.0 Ghz which is the fastest processor speed the motherboard can have. So a bump from 1.9 to 2.0 Ghz wouldn't be significant enough (to me) to overclock. Thanks for the help, i'll post again when I bump it up.

Thank you for the help. I changed it back to 166mhz and the processor is reading as 1.9 Ghz again. It's actually running faster than it has been for the past 2-3 weeks when it originally started running slow. And I knew 166mhz sounded familiar because I used to watch my computer boot because I was waiting to get on and I used to see it posting 166mhz. So anyway, thank you again for the help.
