PCI Device without driver Vostro 1500, Windows XP

I wouldn't be fixing an XP machine unless I had to.  So, I have to.
I cleaned it up of viruses and now it's running fine except:
When it boots it reports "Found new hardware" "PCI Device" and tries to install.  But it can't find a driver.

I've downloaded and installed all of the drivers I could figure might be the case.

The Device Manager doesn't show a modem.  I've installed modem drivers.  No change.

The Device Manager, in System Devices shows a PCI Device with a yellow exclamation point.  It shows:

But, no luck.  Updating driver is the same as the attempt to install at boot.

How to get past this?

Try the modem driver for the Dell Vostro 1400.

This link http://en.community.dell.com/support-forums/laptop/f/3518/t/19298111 describes a similar problem to yours and he solved it by using a 1400 modem driver.

The drivers are here but I'm not sure which one is correct for your system.

THe PCI/VEN code identifies the device as Microsoft's UAA Bus Driver for High Definition Audio on a Dell Vostro 15xx.

With XP you're going to need Microsoft's Hotfix KB888111 to get this running but with XP out of support I can't find a direct download from them. (WindowsXP-KB888111-x86-ENU.exe)

I found a copy here http://thehotfixshare.net/board/index.php?autocom=downloads&showfile=589 which checked clean with AV scanning.  You might prefer to find a copy from somewhere you trust more (some XP HD driver downloads contain the driver as part of the package).

Once installed and restarted then run the audio driver install again.

It's not really the modem driver you're missing but the audio driver provides support for the modem which is why that appears to be missing.
probably that driver is included in the sound driver - so update that one

The Conexant D330 HDA MDC v.92 modem.  It's the same file for the 1400 and the 1500.  I've tried it already.  Still no modem and still an unidentified PCI Device.

I also note that things are not apparently "OK" otherwise.  There's no sound / no sound device even though the audio part of Device Manager looks normal.  Maybe that's a clue.
I have already installed the Microsoft UUA driver.
I've installed all the sound drivers I can find on the Dell site for this computer.  Some of them won't install because they don't like this computer....

I haven't done one of these re: sound in a long time.  I'm wondering what might be suggested next steps?

Well, it's fixed now.  Not a process that I expected nor have ever seen before.
When I was getting ready to do the screen shots, I decided to try to "roll back" the driver on the PCI Device with no driver installed.
As soon as I did that, the PCI Device entry disappeared, which I assumed was temporary.
Then a bunch of the drivers that I had tried to install before, went ahead and installed themselves.
The sound is now working.
AND, the PCI Device is GONE!!
I have the notion that this was a remnant of a parasite perhaps.

Thanks for your help!

This is what fixed it but I can't be sure that the advice given would not have been effective as well.

Good to hear it's fixed  however it happened.
