Lenovo Y550 three 'unknown devices' in driver list and VERY high latencies

[The Raddish]

I have a Lenovo Y550 with the following specs:

    Intel Core 2 Duo processor T6600 (2.20GHz 800MHz 2MBL2)
    nVidia Geforce GT 240M
    4 GB PC3-8500 DDR3 SDRAM 1066MHz
    320GB 5400RPM HD
    1.3MP integrated Webcam
    SuperMulti DVD Recordable
    Intel WiFi Link 5100 1x2 (AGN) WLAN
    15.6" HD WLED Glossy Screen (1366x768)
    Operating system: Genuine Windows 7 Home Premium 64 Bit

I did a clean install when I got it a year ago, and up until a couple months ago it has been running great.  I'm not sure what happened, but streaming video stopped playing smoothly, audio is really choppy, and latencies are so high that gaming is *censored* near impossible on it now.  It used to be smooth like warm butter.

I have done a number of forum searches and have attempted to resolve these issues, but to no avail.  I came across a useful utility called DPC Latency Checker, I've been through all of the suggestions, and still get latencies that average around 8000uSec, but peak as high as 30,000uSec.

I have also recently noticed that I have three unknown devices that do not have drivers.  I can't help but wonder if the two problems are somehow related.

Here is my Everest Home report to get things started.

Nobody has answered. Maybe they don't understand the question.
What is your question?

I did a clean install when I got it a year ago, and up until a couple months ago it has been running great.  I'm not sure what happened, but streaming video stopped playing smoothly, audio is really choppy, and latencies are so high that gaming is *censored* near impossible on it now.  It used to be smooth like warm butter.

Why did you do a clean in stall?
What did you install or change a few months ago?
You have no a backup of the whole system from an earlier time?
Apparently you do not have a a progressive backup or you would have used it and you wouldn't be here posting your problem.

What can I say? It took a long time to develop the Windows OS. Same is true for other OS. Trying to understand what goes wrong days or weeks after the fact is impossible. Unless you have tools and methods that narrow down the problem to a specific point in time.

[The Raddish]

Sorry, I'll try to be more concise.

I have two pointed questions, though one is more appropriate for this forum.

1. I have three unknown devices for which I can not find drivers.  Are there any tools available that can aid in detecting what these devices are so that I can find and install the appropriate drivers?

2. As for the clean install, the computer was sold as coming with W7, but arrived with Vista installed and a license for W7HP.  So I did a clean install of W7HP and downloaded/installed all the drivers from the lenovo site.  Everything was great until a couple of months ago, then things really started slowing down.  There is a delay when typing, I can't stream video/audio content without an incredible amount of choppiness, and gaming is now simply out of the question (freezing/very bad lag, really choppy sound).

I tried going back to a restore point after it first got choppy, but it didn't fix the problem.

[Geek-9pm]

Answer to the first question. You are using Everest, which is among the best tools to identify your hardware.

Second part.
Apparently something happened that is hard to pinpoint. It is very unlikely that hardware would change by itself. (But not impossible.) Sorry that I can not give you an answer. My best guess is that it would happen again even if you did a clean install. So I will not suggest you try that.

But rather than guess, have you looked at the Microsoft Knowledge Base for Windows 7 problems?
Support for Windows 7 technical problems and troubleshooting
Here is a search for unknown device'.
http://support.microsoft.com/search/default.aspx?query=unknown+device&catalog=LCID%3D1033&mode=r
It would seem you are not the only person with this problem.

Can you post a screen shot of device manager?

As for unknown devices...

1.  Open Device Manager (Control Panel>System>Hardware>Device Manager)
   2. The hardware whose drivers are missing will appear as Unknown device, so it's easier to locate the device.
   3. Right click on the unknown device and click on Properties.
   4. Under the Properties window click on Details tab and select Device Instance Id (or Device Instance Path) from the drop down box.
   5. You should see a code similar to this

      PCI\VEN_8086&DEV_27DC&SUBSYS_30868086
      &REV_01\4&1E46F438&0&40F0

   6. The portion of the code highlighted in RED is the Vendor ID and the portion highlighted in GREEN is the Device ID. In this example:

      Vendor ID = 8086
      Device ID = 27DC

   7. Once you have obtained both the IDs, proceed to PCI Database. There you can either search for the vendor from the vendor ID or directly get information about the device along with the vendor name by searching with the device ID.

   8. Then from there you can go directly to the hardware manufactureres website and get the driver.

Broni,

I've used the PCI database in the past but the format for the Device Instance Path I have is different from what I've seen in the past:

HID\IRDEVICEV2&COL06\2&2818A073&1&0005
HID\IRDEVICEV2&COL07\2&2818A073&1&0006
HID\IRDEVICEV2&COL08\2&2818A073&1&0007

Any ideas?

Incidentally, this machine does not have an IR port.

I can see a whole bunch of HID (Human Interface Device) installed.
But....I don't think any of those unknown devices have anything to do with your issue.

I assume, all your issues are related to any online activities, correct?

What are your numbers from here: http://www.speedtest.net/ ?

Are you using wired, or wireless connection?
What type of connection is it and what is your ISP advertised speed?

Broni,

My speeds are pretty solid at ~6MB down, ~2MB up, which is good because that's what I'm paying for.

The network connection isn't the problem.  The same computer booted into XP Pro or Ubuntu doesn't have the latency issues I am seeing.  My problems are exclusive to Windows 7.  I've simultaneously installed both XP and Ubuntu on my system to test this theory after my problems began to manifest and I was unable to solve them through conventional means.  I'm convinced that the hardware is good and my network is solid.

I used to be able to game on this machine in Win7 pretty solidly.  Now, the latencies and lag are so bad that gaming is no longer possible.  I also can not stream any media what-so-ever without incredibly choppy sound, but once the media has completely queued, it behaves normally.  I do not have these problems in XP or Ubuntu on this machine.

I've been through all the basic stuff, and I've uninstalled/reinstalled/updated all of the drivers for  all of the devices (save the missing three).  I've tried a 'repair' installation from Win7 without any change.  I've stopped every process one-by-one to try to determine if a rogue I'd rather not have to do a clean install to abate this problem because I would prefer to understand what is causing the problem.  A clean install is the easy way out.

I've been through all the knowledge bases and so far the best tool I have come across to see the latency issue has been DPC Latency Checker.  As I type this, I am currently averaging just shy of 4000uSec, with a current maximum of 67,245uSec.  Normal range is under 500uSec.  I have three other computers in the house that all operate with normal latencies.

Nearly everything I've read has pointed to device drivers as the culprit.  However, reinstalling drivers doesn't solve the problem.  I've received some excellent advice on this forum in the past and that's why I have returned, hoping for more of the same.

Aside from internet related issues, does the computer work fine in all other areas?

Let's see, if we can find some more info....

Download Process Explorer: http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx

Interestingly, if I tried to run Process Explorer as administrator, it blue screens. :/  Worked fine running it normally.

You definitely have some serious issues.
System Idle Process (CPU not used) should be listed at about 90%, or better.
In your case, it's listed at 7.12%, which means over 90% of your CPU cycles is used by various processes.
Main users are FF at almost 35% and Windows Media Player Network Sharing Service at almost 23%.
Plus all kind of other processes in single digit CPU usage.

What's happening?
It's hard to say right away.
I'd suspect either some hardware issue, or an infection.

I suggest...

As I suspected, my system is free of malware.  I actually was hoping that I had somehow contracted something so that it could be identified and fixed. 

I'm going through some of these suggestions this evening, starting with defragging the hard drive and the registry with Auslogics defrag tools.  I'm open to further suggestions as well.

One thing I noted in the malware thread was that running utilities like Combofix or TFC as administrator immediately resulted in BSODs.  I was able to run them in safe mode successfully, however.
