Have you got any PCI cards that aren't working? Unfortunately from the description there is no way for any of us to tell what the device is. You'll have to check at your end whether there is something that isn't working and needs drivers installed. Because it says it is uunsupported, Windows will not have the drivers, you will have to find what the device is and download the drivers or install them from a disk, if you have the disk.

PS: You can download Everest Home Edition and run it to tell you what devices you have in your machine, and look for something not on the Device Manager listing.

You can use this following procedure to have [Device Manager] view [Non Present Devices] – This may give you a better look at your PC –

Usually the unsupported devices are going to be a Camera – WebCam – Hard Drive Enclosure or Ipod – That is USB Interface/Connection that is not supported by existing drivers or Drivers are not PnP –

Have you tried to Install any of these Devices – Are they Working –

The [Non Present Devices] will be indicated by the [Faded Gray] print – They are sometimes Correct & many times are Wrong – The correct Instances are acting as [Place Holders] for [PnP Devices] that are Installed Correctly BUT are not connected or Powered ON at the moment – (Such as a Printer) –

Many times you will see some of your USB Host Controllers show as [Non Present Devices] – which usually means that you probably have some intermittent USB Issues -

The Incorrect Instances are generally a result of a [Failed Driver Installation] and multiplies as you try blindly try to reinstall the driver – Normally [Device Manager] cannot show these [Non Present Devices] but with this procedure – It can be very useful to clean these [Instances] up –

These [Non Present Devices] are often the remains of an Uninstalled driver – OR - is a Non Supported/Unrecognized Driver -

(8) – Click on [START] Button > Then click on [RUN] –
(9) – Type – devmgmt.msc – and then Click [OK] – This will open [DEVICE MANAGER]
(10)– Click [VIEW] on Menu > Click [Show Hidden Devices] on Pop Down Menu –

Oh thank you for this!! I figured out that the question marks are for my printer?!?!?! How weird.

Probably because I had this printer for soooo long and originally got it when I had Win95. I really botched the install to get it to work on my XP OS because the driver wasn't "digitally signed". Now I am afraid to mess with the yellow question marks in device manager because it was an enormous pain to get my printer to work with XP.

That’s good – Here is the link for Free Home Edition of [EVEREST] – Use it to analyze your PC – Using [Everest] along with Improved [Device Manager] can give you a good viewpoint on your [Hardware Issues]

Just for my information – Were you able to see your Printer as a [Non Present Device] – How many Instances showed up – What is the Interfacing/connection used with Printer – USB – LPT –

http://www.lavalys.c...p?pid=1&lang=en

I thought Tyger posted the link – but I noticed it was gone – There are more Links that [Everest] will give you when you Run the application – There are others also but this is easy to use & do not have to be on line to use –

Good Luck –

I have an uncle who is an elite hacker genius (a good hacker - not a cracker) who happened to stop over my house yesterday and he fixed it. Everything still works! No more yellow question marks. I have no idea what he did.

Too bad I don't see him more often. :tazz:
