Intermittent "buzz" noise

[liamedwards12]

So folks I've had on odd issue recently where while using my PC where i hear an intermittent buzz sound, the sound you hear sometimes when your PC BSODs on you, here's an example of what i mean:

Skip to the 50 second mark.

 

Sorry about the kid in the background, it's the best example i could find, anyways this sound sounds close, but not the same as mine, but i think you get the idea, it happens for half a second sometimes when using my PC when playing video/audio, but the system doesn't stutter or crash and nothing alarming in event viewer, I've checked the files i used to test it and the speakers on another system and have no such issue there so i know it's not a corrupt file and/or broken speakers even though i already thought that this was unlikely, but it's annoying as heck, I've tried a separate windows installation on a different HDD for testing and the issue persists, it possibly could be a motherboard issue but i'm only speculating here and cannot be sure, any help would be appreciated.

Thanks in advance

What does a DPC latency test reveal?

During the "buzz" sound, the latency spikes.

 

 

EDIT: I'll do what the advice says at the bottom and see if any funky drivers are causing it to mess up.

Exactly as I suspected.  Well, that explains the noise.  Now, why is it happening... the answer is probably a bad driver somewhere in the system.  I know it is tedious, but the recommended method is to go through device manager and one by one try disabling something until the problem doesn't happen any more.

I'll report back soon with my findings.

Tried disabling all possible drivers (Except bare bones drivers, e.g. video, mouse/keyboard) and the issue is persisting, i should also note the latency spikes for longer during a driver disable.

Him, that's unusual.  As form the ones that made it worse while disabled, are they up to date?  Is there a new one from the manufacturers website?

I checked to ensure all drivers were up to date and apon calling it a day i shut down my system and woke up, switched my PC back on and the issues were gone, temporarily anyways for about the first 20 mins the issues are nonexistent, then the issue reappears, something i also noted on my test OS i used earlier to troubleshoot the issue initially, however turning the PC off and turning it back on again immediately, the issues were present straight away, i thought it could be a heat issue but the CPU hits no higher than 64 degrees Celsius under AIDA64 for 10 mins and GPU no higher than 76 Celsius in Haven Benchmark for 10 mins. So something with leaving the PC off for a prolonged period of time temporarily resolves the issue it seems, but can't pin down what does that. Also about the drivers i meant that the DPC latency "spikes" during a driver disable (Clicking "Disable" in device manager until the device list refreshes) not when it's disabled as no drivers being disabled improved the problem.

oh, ok.  Yes, I would expect any kind of oddness during the instant that is performs the disabling, but hopefully it runs properly after that

As for the 20 minutes thing, it does sound like something about having the computer on for a while makes a difference.  I've only ever known two other cases of that kind of behaviour:

1. A long time ago when I had an AMD Athlon 64 X2 3800+ running Windows XP 32 bit, dual cores were a fairly new thing still, and as such a lot of programs seemed to have troubles with it.  If I played a game (almost all games), it would start out fine but after an hour or two it would start getting really fast and jumpy.  It seemed to be that for whatever reason the game was running as fast as it could, and would physically speed up (not just fps changes) making it unplayable.  When I set the game to just use one core in task manager, the problem disappeared.  Still, it was similar in that it would only appear after running for a while.
2. I have an issue right now that when I first boot up from cold, the machine will BSOD during boot, but it will then proceed to boot and function perfectly then after (I've had uptimes of over 3 weeks without any issues).  If I do a quick "reboot" it comes up fine, but if I shutdown and then wait a while before starting again, it will do the BSOD during boot again.

I hate to say it but I never did find an actual cause or explanation for these issues.  I could tell you to try random things like switching to a PCI or USB soundcard if you are using onboard audio now, or vice versa, and see how that goes, but usually one of the drivers is the culprit.  The only other thing I can think of right now is to watch the windows logs and right when you start noticing it, check if anything shows up right at that moment.

Alright, i'll be on the lookout for any odd Windows logs, if i cannot find anything over the next 48 hours that could be potentially problematic, all i can think of is a hardware issue of some sort as a clean install of Windows didn't mitigate the problem.

 

I doubt i'll find any funny Windows logs as i never have found any and I've scrolled back for days on Event Viewer etc. and found nothing that could point to a problem, i'll try moving hardware into different slots etc. if that doesn't work i guess i'm gonna send my mobo away for testing and see what results that yields.

 

Also, Ryan_Vickers, i'd like to thank you for your assistance in helping me resolve this issue, i may not reply here if the moving of hardware doesn't yield results, as my mobo will be being tested, but i will reply here once i get my mobo back and tell people for curiosity sake what it was.

 

Again thanks for the help, i appreciate it.
