Solved Unknown Device at PCI bridge

October 13, 2011 at 02:55:00
Specs: Windows 7 Home Premium, AMD Athlon II X4 610e 2.40GH 8GB RAM

Not sure what it does, but it's part of a set of functions like sleep, etc. Shows up as "Other Devices" "Unknown Device" and requires a driver. No driver to be round except from DriverPackSolutions which is a huge download of every driver in the known universe, but I only need one. It's free, but it's a lot of downloading for one drive. Even tho it's apparently a part of the Intel/AMD chipset, Intel doesn't know anything about it.

Neither does Dell. They thought it was a corrupted file in Win 7. It ISN'T because I've found other people on the web with the same problem.

So I decided it was easier to download 3 gigs of data from Russia than to reinstall my operating system in the middle of a major project.

I don't even know what this thing does. Its siblings control sleep, timing, audio, and so on. What this does I believe has something to do with graphics. Just a hunch, but I think it's connected the the graphics card.

I'm not a hardware person: I do software. Tech writer, actually, but having gotten useless advice from Dell (I PAY them for their bad advice ... unbelievable) I found myself googling all over the internet until I actually located this driver.

This is NUTS.

How come nobody knows what these components are or for that matter, what they do? I feel like I'm lost in space, fixing a problem when I have NO idea what I'm doing.

✔ Best Answer
It could be ATK0110 ACPI utility driver.

Your computer may run without it. No big issue. I suggest you visit Windows update to see if a driver is available. If not, please visit your M/B manufacturer web support site and download ATK0110 file.

It turned out to be the IR receiver for my wireless system, part of the AMD component set that live on the PCI bridge. Considering that this is a wireless computer, it's amazing it was working at all. I finally tracked down the driver on yet another website, installed it, and voila, like magic, fixed. It just cost me a night's sleep ... but better that than 2 weeks of rebuilding my system.

You were close ... part of the same set. The problem was that there was no information to tell me WHAT it was, only where it was. But when I saw it was part of a group of components (by address), it had to be one of the little thingies that make our magic computers do wondrous things. If you have an AMD board, then all those components have the same ACPI address ... which is how I knew that it was a real thing and not, as the Dell tech said, a mere image, a ghost as it were.

The technicians at Dell are morons. Badly trained morons. For which I pay a premium. They really do have appalling technical support.

The ultimate problem turned out to be multi-faceted and I solved it myself in the end. Because I was able to catch the blue screen message as it flew by, I was able to determine that the problem was with the video card driver.

Windows update had automatically changed the driver for both my video card and the associated TV component. I downloaded the original drivers from Dell and installed them. The problems disappeared. So how do I define best answer since I provided it myself?

Please note that the answer that someone, not me, marked best answer is not only not the best answer, it isn't the answer at all.
