i think i know whats the problem and its simple the new battery you putted in its busted or not charged properly so try to get a other battery or til you can get a new battery put in the old one cause i think the PC worked well by for you changed the battery.

Try the following steps I'm doing to fix such problem like that or maybe pin point the root cause of the problem or the reason it happened.

1. Try to disconnect all the connection at the back of your computer tower then press the power button of your computer for 15 seconds to drain the remaining power.

2. Reconnect only the power button and the monitor cable then turn it back on. (If the same thing happened go to step 4 if not go to step 3)

3. ( From step 2 ) If it turned back on, most probably the problem is one of the devices that you just disconnected is causing the problem. Try to reconnect then one-by-one and each time you connect them turn on your computer, let's check if it's gonna turn on or not, just proceed until you finish connecting all of the device or until you pin point the root cause of the issue.

4. (From step 2 ) If it didn't turn on, Open up your computer tower and reseat the video card, then turn on the computer

5. If still the same problem, remove your hard drive and turn on your computer, if it turned on, meaning that the hard drive might be the problem, if not, just put it back in

6. If still the same problem, remove the memories from your computer, if you have more than one memory installed remove them all, test the first memory to the 1st slot and to other slots one-by-one, see if it turned on. Test the second memory and so on, to the 1st slot and so on. Do it only with one memory testing each memory.

7. Reseat the power cord coming from the power supply, the 21 pin and also the small one that is plugged into your motherboard,

8. Reseat the CPU

9. If all of those things failed, most probably that the power supply is causing the problem. it's also possible that the motherboard is affected, I hope not.

hi you have a faulty driver.
1) try to uninstall it from the device manager, restart the pc.
wait for it to FOUND NEW HARDWARE !!
follow instruction on screen and reinstall drivers,
2) you can go to IBM web page , look your model or serial number from your pc and download the latest driver for sound card. and install it. it should work

yes ofcourse you can download it from www.isohunt.com.
search there for windows xp sp3 and download it using vuze(you have to download it from the same site before downloading iso image of windows xp sp3)

You know , you could just ask a friend for their cd or download one online

As long as you get the version and service pack number right it should be fine

And its perfectly legal , providing you use your own product key!

Back up all your data and do a system restore

I would replace the whole power supply. You don't want to give it a chance to short out the board. If this is a just a run of the mill business machine the power supply should only be around 50.00 or less depending on where you find it.

If the pins are bend straighten it using squeezer
