Stuttering/short freezing every few minutes (if sound is playing, the audio goes all cracking and weird sounding.)

    Question

  • I usually can figure stuff out on my own but this is so unusual. It started happening when I installed a game (I have already uninstalled it.) I figured it was nothing at first but it's just getting annoying now. Just ask for whatever information you may need to help me fix this. I'm running Win 7 64-bit on a laptop.

  • Try using LatencyMon to figure out where the problem lies, documentation pages listed at the foot of the page.

  • Uhhhh what? How do I use that? I can't even find the download.

    Install it, start monitoring (arrow under File), use the computer normally for 10 minutes or so then stop monitoring and check the data under the Stats, Processes, Drivers etc. tabs.

  • This doesn't look good to me. I don't understand how to find the source of the problem, though.

    CONCLUSION
    _________________________________________________________________________________________________________
    Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines belonging to a driver running in your system appear to be executing for too long. Also your system appears to be having trouble which may be attributed to SMI routines, CPU bugs or unexplainable CPU stalls.

  • Ok, looks like there's a problem with a driver, to find out which, follow the instructions carefully at this page (for a similar tool).

    There's also a possibility that malware could be causing this especially if the game that seemed to trigger this behaviour was cracked, repacked or required a 'No CD' patch.

    Thursday, March 01, 2012 10:41 AM
  • I've downloaded and played the game before with no problems whatsoever. I also did plenty of scans already and pretty much ruled out the possibility of it being malware. I figured it probably had something to do with a driver.

    EDIT: I tried disabling pretty much everything except what it said not to do. I don't get it though, it said not to disable anything under system devices, but it said there's things in there to try disabling.

    • Edited by BrewerD Thursday, March 01, 2012 10:56 AM
    Thursday, March 01, 2012 10:43 AM
  • OH, I remember at that same time I was trying to fix my mouse because for some reason it would not work. Could the drivers/whatever for that be causing this?
    Thursday, March 01, 2012 11:12 AM
  • "Disabling pretty much everything":[quote]After you disabled a single device, carefully watch DPC Latency Checker. When excessive latency values disappear you found the responsible device driver. If there are still exceptional large DPC latencies try the next device.[/quote]Read the page again carefully, try to be logical in your testing.

    If it's the mouse drivers you suspect, try rolling back the drivers in Device Manager.

    Thursday, March 01, 2012 11:17 AM
  • I tried disabling it altogether and got nothing.. Is there any way I can narrow it down by going into safe mode?
    Thursday, March 01, 2012 11:21 AM
  • Windows Safe Mode uses a different set of drivers. Please, read the pages I've already linked you to. Test one disabled/updated/rolled back device at a time. Once you change the bad device driver, you will see a change in LatencyMon and DPClat.
    Thursday, March 01, 2012 11:25 AM
  • On some it prompts me to restart the computer. Is that necessary?
    Thursday, March 01, 2012 11:32 AM
  • Yes, if the driver is in use and it's needed for system stability.
    Thursday, March 01, 2012 11:33 AM
  • Okay, I'll just need a couple more minutes to retest some of them then.

    EDIT: Done and I got no change from disabling anything.

    • Edited by BrewerD Thursday, March 01, 2012 11:46 AM
    Thursday, March 01, 2012 11:35 AM
  • Here is everything in my device manager. I pretty much tried disabling every from the list one by one and it never changed those spikes. The only other thing I can think of doing is formatting my computer but it didn't come with a disk (is that normal?)

    EDIT: Some driver files giving high DPC are HDAudBus.sys (High Definition Audio Bus Driver). USBPORT.SYS (USB 1.1 & 2.0 Port Driver), and iaStor.sys (Intel Rapid Storage Technology driver x64.) I think that last one was installed around the time I started getting these errors.

  • Hi,

    The freezing issue can be caused by many factors. You can try the following methods to narrow down the issue.

    1. Test the issue in Safe Mode. What is the result?
    2. Test the issue in Clean Boot. What is the result?
    3. Update BIOS, chipset, device drivers from computer manufacturer such as Dell.
    4. Scan for viruses and malware

    Thank you so much for your reply.

    1. I will do that in a minute.

    2. What is a clean boot?

    3. Do I update the BIOS from the dell site as well?

    4. I've already scanned and got nothing..

    EDIT: How do I test it in Safe mode? I usually just play a video or something but I can't use sound.

  • Hey guys. Got the same problem or more than a year by now. Can not do any video edditing, audio...it might freeze for a sec or two. Changed Hard Dirve, reinstalled the system, formatted, Installed 7 professional. Didn't help. 2 days ago got the new motherboard and graphic card...didn't help. Dell gives no help either. And I am no stranger to PC, but cant figure this out. Anyone has any solutions?
