Windows 7: video players kill USB

I have a new Intel DX79T0 + i7-3930K 64 bit CPU machine with 16 Gby mem and an SSD. Certain video applications -several different players and format converters - will kill the entire USB: mouse, keyboard, external drives, hub, everything (both the USB 2 and 3 ports). I am using the latest K-Lite codec package. Has anyone else seen this? Any ideas on how to correct.

Does this occur if you have ONLY the mouse and the keyboard connected?

Thanks for the suggestion (which I should have thought of), however, no, that does not help. VLC player is the most consistent offender, as is the media player that comes with K-Lite codecs. Microsoft Media player does not (so far) seem to have the problem (which is my current work-around).

Uninstall the K-Lite codecs.

Uninstall VLC.

Run System File Checker.


Reinstall only one of the two programs you uninstalled.
If failed, then you know the offender.
If success, install the other program.

If failed, then you have the offender.
If success, then System File Checker fixed your problem.

System File Checker – SFC

System File Checker checks system files and restores them if possible.

System File Checker places results in:
%windir%\logs\cbs

My preference is to empty the abovementioned folder BEFORE I run SFC.

How to empty the “results” folder
· Run CMD.EXE as administrator
o WIN | type CMD.EXE | do NOT hit ENTER |
o CTRL + Shift + ENTER key combo | YES button
· Type following commands, each followed with ENTER key
o CD %windir%\logs\CBS
o DEL *.*
o EXIT

To run System File Checker:
WIN | type CMD.EXE | do NOT hit Enter| CTRL + SHIFT + ENTER key combo | YES button
WIN is the key with the Microsoft flag on top.

Enter SFC /SCANNOW
When System File Checker finishes---

If you do not see:
Verification 100% complete.
Windows Resource Protection did not find any integrity violations.

Then:
Ø Type EXIT to return
Ø RESTART your computer
Ø Run sfc /scannow again

If you do not see:
Windows Resource Protection did not find any integrity violations.

Then:
Ø Type EXIT to return
Ø RESTART your computer
Ø Run sfc /scannow again

If you do not see:
Windows Resource Protection did not find any integrity violations.

Then:
Ø Type EXIT to return
Ø RESTART your computer
Ø Run sfc /scannow again
Notice that you have run sfc and restarted your computer up to three times.

Ø If all did not go well, you can use
the findstr command to view the results.

VIEW THE RESULTS
Put the System File Checker (SFC) results in a File on the Desktop
findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log > %userprofile%\desktop\sfcdetails.txt
where /C: specifies the desired search string

This finds the primary results. More info can be gleaned, if necessary, by examining the entire cbs.log file.

And of course, there is an excellent tutorial on SFC:
SFC /SCANNOW Command - System File Checker

as far as i know VLC uses internal codecs.

I had already uninstalled k-lite and then VLC. I have concluded that this is a more general problem than I originally thought (even Windows Media Player occasionally tickles the bug). It is also the case that the USB freezing was just a side effect of the whole system freezing (perhaps a CPU halt because the graphics boards probably maintains the framebuffer state and displays the last screen before the halt).

I took your suggestion of running sfc multiple times. The first time on reboot 9 updates were installed. Subsequent runs reported 100% verification, however the log was still reporting what appear to be system file replacement operations - e.g.:

POQ 119 starts:

POQ 119 ends.

(In fact I see this same set of moves in every run.)

In any event, thanks for your expert advice. I will run for a while and see if the repairs have stabilized the system.

Yes, that is my understanding as well.

It is the media player that comes with the k-lite codec distribution that uses the k-lite codecs.

Bill,
What's the status now?

re: What is the status now?

I have reinstalled VLC and k-lite, one at a time, and they both still lock up the system, though they are considerably more stable than before.

In the process of trying a range of available media players, I have found that the most stable (I have yet to get it to tickel the bug) is Apple's Quicktime. Though it will not play all formats, the DVD Catalyst 4 software will convert most any format to mp4 and, unlike some of the other similar tools, this software is also stable.

I suppose that what I should try next is to reload the OS. (I will have to get a copy of the media from the fwllow who assembled the system.)
THis is not too bad a time to try this because the system is new enough that I don't yet have a large amount of software loaded.

Unless you have any other suggestions ......

Thanks, Bill
