For a while now (It took me a while to actually start to trouble shoot) my HTPC that I built in March of 2011 has been making buzzing/shuddering noises along with video lag.

Anyone know what could be causing this?

I have a video, read the description for specs. and things I have already tired. I think its probably a bad PCI-e lane or some mobo problem.

Buzzing reminds me of an irq conflict.

Shuddering reminds me of a fan or unshielded speaker being to close to an old tube tv.
Does the shudder happen when watching non-htpc generated content like from the cable/sat/ antenna ?

this is like a electrical buzzer could be the power supply fan when you ask more power

I once had a system that did that at random, of all things, the sata controller + a bad firmware was to blame.

Does the cpu usage change when this happens? Just open the task manager to see.

My Media Center has the same sound card(I assume the onboard alc 892), and it has been fine for years.

It is also worth ensuring ALL drivers are the latest grab those from asus and the video card driver from AMD/Nvidia or intel(depending on card) .

I would like to mention that the buzzing sound comes from the speakers. Also I took apart one of my other computers, removing the mobo etc, but leaving the PSU and fans etc.... And took the mobo, CPU, ram, and HDD from the "buzzing pc" and put it in that case of the perfectly fine pc, in a whole different part of the house and it still has the same issue.

that means the motherboard sending this to the speaker check if there is no default on the motherboard coil ,capacitor or something else that do not look normal even power connector

Also the audio/Video is connected to the HDTV via HDMI through an ati hd 5670 this is why I suspect a bad pci-e lane. Maybe I should also try a bios update. I will also try a clean install of windows and see if it makes a difference. I will again do a visual inspection of capacitors and such.

Have you tried to disable the onboard audio if you are using the 5670 for audio.

Disable it in the bios and make sure you have your latest ati drivers as well.

That sound is normally a conflict or other software issue. Back in the old days it also told you it was time for a faster computer :)  P133 did that from time to time. Funny thing is other systems did it worse(Thank you SoundBlaster 16! you let that computer do awesome things).

Lol thanks, I will try that and let you know how it goes. Also a question I have is when you build a new 'puter what drivers should you let windows install automatically vs. downloading from the mobo website? I always download gfx card drivers, sata drivers, USB 3 and audio drivers.

I get it all off the website(Asus,gigabyte)

My audio drivers are actually from Realtek for my media center as new ones disable jack re-tasking on most plugs.

For my gaming system drivers from Creative as what is on the CD is obsolete already.

I used to get LAN drivers of the CD/DVD if needed(but thats not common as windows has most basic lan drivers)

That last thing, i generally get my chipset drivers from Intel or AMD's(and back in the day via....ewwww) site as they are newer.

I went into the UEFI bios and disabled the on board audio, but it's still buzzing :(

do you have onboard video that you could use and remove the hd 5670 and use onboard audio to see if it is not the audio part on graphic that cause this,since you got a spare pc would try to switch only the graphic card from one to the other

On this board there is a PCI-E x16 slot, two PCI slots (old school slots) , and another PCI-E x16 (runnig at x4). I have my HD 5670 in the first slot running at x16, and in the other PCI-E I had my Asus wireless N card. I took the wireless car out and powered up and played some music in itunes, some video in windows media player, and a PC game. After about 15 minutes of testing with the media, there was NO BUZZING. Maybe I need a BIOS update?

I used the on board audio and the DVI port on the hd 5670 instead of the HDMI and it worked fine (but I don't recon if the wireless card was installed when I did that)

Unfortunately, the Asus website lacks any bios updates for the CSM version of the board. I would suggest contacting them to see if they have any updates for your board.

had something similar with wireless card on forum a few weeks ago put back wireless card to the bottom slot on motherboard and turn antenna sideways so the wont send signal to the audio output also if you can chance the audio cable for shielded one

That seems to be what the problem was. I put the wireless card back in and it started to buz randomly again. I disabled the card in adapter settings, and BOOM no more buzzing! :lol:  the only problem with putting the card at the bottom pci port is that it's a micro ATX board, and it already is on the bottom slot. I guess I'll have to pick up another netgear power line adapter or just wire my house with eathernet. Or just look into a shielded HDMI cable.


Thanks sooo much for all the help and input. I even called for an RMA number before I posted this thread, but for some reason I never received the email with the RMA info. Well I guess everything happens for a reason.

Thanks again!

I want a picture of this mod :) 

I kept some shielding(its already cardboard on one side :)  ) from old external drives for this kind of thing.
