Possible CMOS Battery problem???

[Sircoop]

I am runnng

Win xp home Sp1
AMD XP 2000 266FSB
Soyo Dragon Plus (With newest Bios)
twin 120gig WD 8mb Cache IDE Hard Drives
512 PC2100 DDR Sdram
Ti4400 128MB AGP Video Card
Creative Augilogy gamer

Here is my problem

Some days my PC just boots up fine and it runs stable doing many things for days!

Then like today here is what happens

I boot up and am using the PC for a some time and THE system just reboots itself.

Then it trys to reboot and says CMOS Checksum error defaults loaded.

I enter the BIOS and the CPU feq is set back to 100MHZ..I change it and reboot, maybe it works maybe it does not..

Then another time the pc just beeps super fast for about 3 secs and then nothing happens...All fans are, HDDs etc...

Some other time the PC just locks up/hangs during boot up...It is like hit or miss.

Right now I have been using the PC for about 2 hours after I failed during boot up for about 1 hour!

Things I have done

Checked memory overnight...no errors.
PSU looks good. Is there a program I can download to really check?
Cleared CMOS and rebooted

Many my CMOS battery is dying?

How do I set XP to blue screen me instead of rebooting?

any advice is welcome...

Wow, not sure what is going on.

In cases like this its important to try to get your system down to basics, see if its stable there, then add things one at a time.

Can you set your bios back to a default "safe" level (best stability, not best performance option)? Also, if you have anything overclocked or overvoltaged set those settings back to default.

Also get a bootable floppy (can go to Boot Disk.com if you don't have one).

Make sure you can boot from your floppy and you don't go into Windows. Now boot the system and see if the problem remains. If so unplug all peripherals from your system including PCI cards, CD Roms, USB peripherals, Hard Drives, etc... leave only your fans, CPU Fan, floppy, RAM, and video card in place.

Repeat booting to your floppy and see what happens. If your system is OK, then add one peripheral at a time (booting off of your floppy so you don't go into Windows and screw up your plug n play settings) and see what happens.

Let me know how this works out. It may also be a CMOS battery problem, or something in your CPU not likeing the 133 bus setting.

Could be a million things. [Great help I am]

Firstly, BIOS resetting itself may show the battery has come to the end of its lowly existence.
The resetting itself may be due to CPU overheating, or a system fan not spinning at its default speed.

Firstly, change battery.
See what happens.
If you can get hold of any mobo [pref. manufacturer's] software to do checks and configuration.

Good luck

Well I just reset my BIOS and changed the battery and still I have the same strange problems. I have no idea.... Next I guess I will try new memory.

Hey when the blue screen pops up instead of system failure reboot(I removed it) it says equal less then zero etc....

Then I get long beeps a pause and then long beeps and a pause.. Then if I wait a few minutes. I can boot, but ,my 2000XP is read as a 1250XP and then I go into the bios and switch it from 100MHZ FSB to 133 FSB and reboot...

Any other ideas out there?
