Hi, BleepingComputer experts, I'd like some assistance. For a few days now, my computer has been doing something strange. Once every few minutes to few seconds, it freezes for less than a second and then carries on normally. Any audio coming from the speakers becomes a buzzing noise and videos, YouTube or otherwise, stop, then continue like nothing happened after the computer recovers. The computer is only three weeks old so I doubt I have hardware going bad, but multiple MalwareBytes scans return no malicious content and SpyBot S&D doesn't come up with anything either. It's been maybe three to five days, I think. I'm running Windows 8. I'm not that great with computers- especially not Windows 8- so please try to keep your instructions simple. It's probably not a big deal, but it's pretty irritating and I'm worried that it could be something nasty. Thank you in advance!

Did this start happening from day one? Freezes like that are usually related to hardware issues. So to begin with, lets try scanning with chkdsk. Do the following to scan with chkdsk: 

 
 
  • Go to my computers and right click on C: drive. 
  • Go to properties - Tools - Check now. 
  • A new popup will come up, check the second option in it too. 
  • It will ask for a restart, do yes. 
  • Continue the above steps for every drive you have. 
  • Note: This process will take some time to finish! 
    A log will be generated. Paste it here by following this tutorial. 
     

     

    Regards,

    Abcd.

    Before I scan with chkdsk, I'd like to mention that this is a new thing that only started happening in the last few days, not from day one, though like I said, multiple MalwareBytes scans- full and quick scans- and many SpyBot scans return no results indicating malicious content. It's more annoying than worrysome but I am trying to rule out the possibility of it being a virus, since my last computer bit the dust due to a virus.

    Can you remember what all you downloaded/installed in the last few days? Any which ways, we should go ahead with the chkdsk scan.

    Haven't downloaded or installed anything aside from SpyBot within the past few days, which I only installed after the problem began. This install of Windows is pretty much fresh; all I've installed on it from day one (that I recall) are Winrar, a couple of games off disks, iTunes, MalwareBytes, Firefox, and SpyBot. (A full MalwareBytes scan of the C: and D: drives returned nothing and SpyBot is still giving me nothing.) I'll run chkdsk in the morning- it's late. Thank you very very much for at least pointing me in the right direction!

    I will be waiting for your chkdsk results. :)

    Ran chkdsk on the two drives I have, no errors returned. Still nothing from MalwareBytes or SpyBot.

    Interesting. Lets give a thorough check to your computer for any infections using OTL. Please do the following: 

     

    • Please double-click OTL.exe to run it.
    • Make sure all other windows are closed to let it run uninterrupted.
    • When the window appears, make sure that you set the following specifications:
    • Output = Standard Output
    • Processes = Use SafeList
    • Services = Use SafeList
    • Standard Registry = Use SafeList
    • Modules = No Company Name
    • Drivers = Use SafeList
    • Extra Registry = Use SafeList
    • Check the LOP Check and Purity Check boxes.
    • Click the Run Scan button. Do not change any settings unless otherwise told to do so. The scan won't take long.
     
    When the scan completes, it will open two Notepad windows:
    OTL.txt
    Extras.txt
    These are saved in the same location as OTL.
     
     
    OTL logs are going to be big, so upload them to some pasting site like http://justpaste.it/ and post the link here. 
    Note: Upload both the OTL and Extra logs. 
     
     
    Regards,
    Abcd.

    Wonderful. Thank you! :)

    I don't see any infections in those log files. But I would like to ask you, which Windows OS are you running? Because for some strange reason, OTL wasn't able to detect the Windows version you are running. This brings us back to hardware. 

    Download GSmart Control, open it and go to the attributes tab. Click on View Output and paste everything in it over here. 

     

     

    Regards,

    Abcd.

    Like what kind of error? Have you downloaded the version with GTK+? Specifically this one?
