PC slow, freezing up, and sound breaking up/choppy/warped

For a few months now I've had problems with my PC freezing up randomly. That is, video and audio halt for half of a second or less. Sometimes I'd even get blue screens. After getting a new hard drive and video card, I stopped getting blue screens.


Now, in the last few days or so, my audio has been breaking up, getting interference, buzzing noise and all that. At first it just happened randomly, now and then my audio would stop working for a few seconds. I'd reconnect my headphones and it would be fixed. But now it's a constant thing and I can't seem to fix it.


My windows is fully up to date, video card drivers fully updated (I get emailed when they release updates), motherboard driver updated, etc. I also have done full intense scan with Kaspersky antivirus and found nothing. At this point I'm thinking its either a bad motherboard or bad RAM since I've replaced my GPU and HDDs recently. But I have no idea.

My PC has been freezing a bit and starting up really slow as well. I haven't downloaded anything recently or installed any new programs either.


Any help would be appreciated.

  1. disable windows auto updates and auto driver updates.

    could be a sound driver conflict. go into the device manager and uninstall the HD HDMI sound that was installed with the amd graphics drivers.

    what happens?
  2. There isn't an HD / HDMI anything on the list. I don't use the HDMI ports with my monitors setup, I use DVI. Also, I've already had windows set to check for updates but not install/download them automatically.

  3. amd high def audi..... that would be the hdmi.
    if you remove it windows will reinstall on start up if you don't disable auto driver update ( different than windows update ).
  4. I uninstalled the "AMD High Definition Audio Device", and disabled the Auto Driver updates using this guide I found on google.

    After restarting, nothing has changed. Audio still messed up, pc takes forever to load still.
  5. reset cmos

    and is the ram all the same?


    what is the power supply?
  6. All ram is the same model : http://www.newegg.com/Product/Product.aspx?Item=N82E16820231277

    Resetting CMOS seemed to help for a few minutes, but then audio started messing up again. And my computer rolled back to late 2012 which I wasn't expecting, so I lost quite a bit of data now..
  7. change battery. try another "quality" power supply. did you read the reviews on the one you have?
