I am runing XP Professional on a HP dc7700. I have no sound and I get an
error message when I try and use the DVD. The Device Manager has a yellow
question mark over each of the PCI modules. How do I download and/or install
PCI drivers for this machine? I believe the machine has a realtek sound
driver.
This is to answer the question "where would I get PCI drivers if they're available".
A certain number of items come from the chipset. So a chipset driver can
help the OS identify and install other stuff. For example, the OS probably
has some generic PCI bridge drivers built in. That is why, to some extent, what
you're seeing doesn't sound on the level (i.e. it is a side effect of
something else - I cannot imagine the chipset drivers actually being
missing). Maybe your ENUM registry key got deleted, and the OS had to
enumerate everything all over again ?

The first hit I get on HP, is this one. It says the computer uses the
Q965 chipset.

A picture of the basic chipset. There are likely some options for the
ICH8 (RAID or no RAID supported).

To find chipset drivers you can start here.

Chipsets : Chipset Software : Intel Chipset Software Installation Utility
I like the ZIP format, because I can look at it, without installing it.

965g.inf
ich8core.inf
ich8id2.inf
ich8ide.inf
ich8smb.inf
ich8usb.inf
Those are potentially some of the files that might be involved
when you install the chipset drivers. The Q965 is a 965G with
support for remote management of the computer. (There is a
microcontroller in the chipset, which can be reached via the
Ethernet interface, so some form of remote control is possible
by the IT department.)
You can use the "setup.exe" at the top level of the chipset
installer, to do the install.
I thought things like PCI bridge were part of WinXP, so it is
a bit of a mystery as to why you're seeing those symptoms.
I'd probably have a look around, in Event Viewer or setupapi.log
and check for evidence of some other kind of problem.
Either the sound problem is going to resolve after you
fix your other driver issues, or you're going to need
the sound driver from the HP site. For HDAudio, sound
consists of two component parts. UAA is the Microsoft
component (included in SP3, available separately otherwise).
And then a chip specific part, which would be part of the
driver from HP. Usually, for convenience, the HP download
includes the UAA hotfix as part of the installer. I'm
assuming your sound is HDAudio - if it is a separate sound
card, then the driver would be specific to that card
instead.
