Sudden lag spikes with buzzing/screeching

I have an HP ENVY 15 laptop with Windows 8.1 that I've been using for two years (forced upgrade to 8.1 sometime during then), and in the past few months, it started doing this.


So, for quite a few months now, when I am playing Dota 2 or watching youtube videos, my computer will suddenly lag and a screeching noise will come through my headphones. It essentially freezes up and I have trouble getting the mouse and keyboard to respond as well. After about a minute of screeching and intense lag, it slowly starts working again. All four cores of my CPU shoot up to 100% during this and after a minute go down again when the lag ends.


I searched the internet and found this archived thread about an ASUS laptop that was experiencing the same problem as mine. http://rog.asus.com/forum/archive/index.php/t-1496


In that thread, they seemed to think the network drivers or Mcafee was causing the problem. I don't have Mcafee, and I updated my Realtek LAN drivers, and the problem has not gone away. In that thread, someone posted a youtube video showing the lag, and it is exactly the same thing that is happening to me:
https://www.youtube.com/watch?v=VZdmM1qjLxk
At 1:35 and 2:10, this is the exact awful sound I'm hearing, accompanied by insane stuttering on my computer.


Here is my msinfo32.nfo file for those interested. I'm not sure why Google Drive thinks it's an audio file but it can be downloaded.

I also found an old thread where someone seems to be experiencing the same thing, and it's the exact same symptoms. Thankfully, I guess this means that it isn't a hardware issue.

Most commonly this sort of error is associated with video driver problems.

So, please uninstall your video drivers, then download and install the latest, Win8.1 compatible video drivers for your system from the HP support website.

 

Your UEFI/BIOS dates from 2014, please update it from the HP Support website:

 

BIOS Version/Date    Insyde F.65, 11/20/2014

Manually search the HP Support website page for your model - and use the HP Support Assistant software on your system to see if there is a later version.  You must try both ways, as the latest version doesn't always show up in both.

 

Lot's of Windows Updates failures in the WER section of the MSINFO32 report. If the problems continue, please post over in the http://www.bleepingcomputer.com/forums/f/209/windows-8-and-windows-81/ forums for help with this.

 

Uninstall Daemon Tools temporarily - it may be interfering (as I've seen video errors due to it).

Here's my canned speech about it:

 

Daemon Tools (and Alcohol % software) are known to cause problems on some Windows systems (mostly due to the sptd.sys driver, although I have seen both dtsoftbus01.sys and dtscsibus.sys blamed on several occasions).

Please un-install the program, then use the following free tool to ensure that the troublesome sptd.sys driver is removed from your system (pick the 32 or 64 bit system depending on your system's configuration):  New link (15 Aug 2012):  http://www.duplexsecure.com/downloads (pick the appropriate version for your system and select "Un-install" when you run it).
Alternate link:  http://www.disc-tools.com/download/sptd
Manual procedure here:  http://daemonpro-help.com/en/problems_and_solutions/registry_and_sptd_problems.html

 

If it doesn't stop, then Please do the following:
- open Event Viewer (run eventvwr.msc from the "Run" dialog)
- expand the Custom Views category (left click on the > next to the words "Custom Views")
- right click on Administrative Events
- select "Save all Events in Custom View as..."
- save the file as Admin.evtx
- zip up the file (right click on it, select "Send to", select "Compressed (zipped) folder")
- upload it with your next post (if it's too big, then upload it to a free file-hosting service and post a link here).

Thank you so much, I will do those things! By the way, I noticed that when this lag happens, my CPU usage jumps to 100%, and looking at the Task Manager, audiodg.exe is top in CPU usage with 10-20%, while all my other processes have 1-5% CPU (every single one). Could this audiodg.exe be to blame?

While it's possible that it's to blame, it's also possible that something else is causing it to act that way.

It won't hurt to uninstall your audio drivers, then download and install the latest, Win8.1 compatible audio drivers for your system from the HP support website.

 

FYI - the audiodg.exe file is a Windows file, and it's protected by a number of different Windows functions.

As such, it's not likely that this is the root cause.
Trying to replace the audio files is a start, but may not be the solution.

Yeah, I did uninstall and reinstall, but it didn't help. Also, the BIOS sadly is already the most updated version...HP isn't great about rolling out lots of updates.

I've uninstalled Daemon Tools and used the program, It said that SPTD was not found, so I guess that's a good thing. I'll test and see if it still happens. By the way, in my original post, I linked to some info that seems to say that this problem is sometimes linked to network drivers. I have updated my network drivers and the problem persists unfortunately.

Unfortunately the problem is still there even after uninstalling Daemon Tools.

Fixed it! I did a system refresh (basically a full restore that leaves your documents there) and the problem is solved!
