Sound Driver Problem Since Formatting And Installing XP Pro

Hello, I purchased an eMachines t3958 not long ago, which came installed with Microsoft Windows XP Home Edition. I recently reformatted, and installed Windows XP Pro as I needed several features it offered which home edition did not.
After reformatting, my sound no longer works. I've tried installing the drivers for my motherboard, as I have on-board audio, from the intel website. My motherboard is Intel Celeron D845GVSR, and ive tried the most recent drivers (Realtek AC97), but when installing the driver the computer hangs up on the file "RtlCPAPI.dll" and then it restarts the computer automatically. It does not finish installing the drivers, and in device manager it says the device has a problem. The device does have a yellow exclamation point next to it in device manager, seemingly having a conflict.
I ran msinfo32, and it showed a sharing/conflict between the audio and SMBus controller, as they both use IRQ 3. I tried disabling the SMBus controller, but still couldn't install the drivers successfully. Next, I went into the BIOS and disabled all features except for the audio, and still could not install the drivers.
Also, I do not have a restore cd which contains the driver, though I feel this problem is more related to the conflict issue than the driver files.
I am unable to change the IRQ setting for the audio and the SMBus controller, so is there anything I could do to resolve this issue? Any help would be greatly appreciated!

Use the machines Restore CDs then use your XP Pro CD to upgrade the OS.

No Restore CD, and Doesn't Support Upgrade

In reply to: The easiest upgrade.

I attempted to upgrade from the original installation but it didn't allow me, it made me format and clean isntall. I was not provided with a Restore Cd. They only came with blank cd's in a restore pack, that inside suggested I create some restore cd's. I never opened the pack, assuming it WAS a restore CD, so didn't know that I was supposed to create my own cd's until after I'd formatted.

You gaffed it.

Those restore CDs could have the required drivers. The last time I did this, I just used those to get the drivers.

Sorry to hear that you'll have to slug it out with the maker now.

Next time? Make those CDs.

Disable the onboard sound, install a sound card.

May Have To, But Maybe This Helps

In reply to: A solution.

I tried deleting the SMBus controller and the Audio controller, restarted to install them and after beginning installation of Realtek Audio Drivers I got the following blue screen of death:

"A problem has been detected and windows has been shutdown to prevent damage to your computer.

If this is your first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:

Check to be sure you have adequate disk space. If a driver is identified in the Stop message, disable the driver or check with the manufacturer for driver updates. Try changing video adapters.

Check with your hardware vendor for any BIOS updates. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode.

Technical Information:

*** STOP: 0x0000007E (0xc0000005, 0xEEA32460, 0xF8989AA0, 0xF898979C) ***

That's the missing motherboard drivers. Try..

In reply to: May Have To, But Maybe This Helps

Find AIDA32 and find out what chipset the machine is based on. Install the mothereboard drivers.

Remember that Microsoft doesn't do drivers...
