By removing the battery you've already set the CMOS to
default....there is no need to "jump" anything.
Restart and enter the BIOS...correct the date and let the BIOS
redetect all hardware...double check to see that it matches what you
have. Reboot and let it start whatever OS you are using...Go to Device
manager and check to see that all devices are functioning.
That's it..............
Any Customizations that you had before will need to be redone...but
first make sure "default" works..!!!!!!!!

Good grief! How did I miss that? Good catch lol

OK, there are 3 pins on the jumper. Should I first try to start if
up and see
if everything comes up fine? Or after I start it up go into BIOS and
then switch the jumper from 1 & 2 prong to 2 & 3 prong for how long
and then switch them back. Ok, I just want to know after firing up
the PC, when to start the jumper procedure.
Thanks,

Ok, I found out all I needed to do was to change the 3 volt 2032
motherboard battery and all would have been ok. Instead I reseated
the RAM sticks, changed the power supply, changed the video card,
changed the IDE parallel straps, changed the monitor, changed the
hard drive, and finally took out the motherboard and removed the
heatsink and fan asembly off the CPU chip and checked the chip out.
After all that it turns out the reason the PC stopped working was
the little 3 volt battery on the motherboard. It worked again for a
little while, maybe a day after I changed the monitor. Just like a
flashlight that is going dead, after you sit it for a while the
next day you will get some power and it will work for a while and
then dim out. Tell tail signs of battery failure. By accident I
was checking this new battery checker device that I bought from
Home Depot and I needed batteries to check to see if the settings
worked and found out the battery wasn't working.
Ok, now lets get to the CMOS. There is a CMOS jumper on the
motherboard
that I see. What do I need to do to the jumper or do I need to
physically do anything on the mobo or just go into BIOS and
configure something there?
Any help will be greatly appreciated.

Go to the mobo mfg site and look for instructions on same. Are you
sure that's what it's for? Make certain. Get the wrong one and
you could possibly put improper voltages on something. Get the
instructions for that mobo somehow, if you have to look on EBay and
Craig's List for them.
Most likely, and it won't hurt anything to try:
If the jumper is on a header with only two pins:
remove it, wait about 60 seconds, replace it. CMOS should be
reset. If there are 3 pins in the header:
Pull the jumper off as above and replace it; see if it did
anything. No?
Put the jumper on the OTHER TWO pins for 60 seconds. The put
back in original position.
See if it helped.
More than 3 pins in the header? STOP! Don't mess with it. Either
it's the wrong one or there's something special about it.
