I suggest a system wipe to rule out software issues. If that doesn't fix it then it's the motherboard keeping the audio and video circuits too close without proper shielding. In which case you might consider an RMA.
In unrelated news my computer has also been acting very strange lately. I won't go through it all since like most of my hardware issues it's a long and strange story filled with lots of debugging work (if you can call it that). Long story short I will probably be RMAing my graphics card soon and living off my HD 4000 IGP for awhile. My entire system would freeze and crash whenever playing a game (sometimes even at the 2D menu screen). I tested this with multiple PC games and it's always the same. Graphics get really fucked up (checkerboard pattern with brightly colored patches speckling randomly and some patches of normality), audio starts looping endlessly, the video and audio freeze, and the entire system becomes unresponsive to any type of input. I got it to recover one time by quickly alt tabbing out of the game. It froze for a few minutes then gave the standard "nvidia display device driver has encountered a problem and has crashed" error message that I was expecting. I logged the GPU stats during one of these events and temperatures and clock rates were all normal. I even cleaned out the gpu cooler and replaced the paste just to be sure. Eventually it started doing it whenever I tried to boot the OS causing it to crash everytime. One time it even did it during POST somehow. By switching to my IGP I can boot again but it's still acting funny sometimes. The monitor flashes for a few seconds when waking up from sleep. And it flashes the entire time during the OS boot until it reaches the desktop screen, where it then goes away. So it could still be the motherboard I suppose. But the graphics card is more likely. I'll test another card to be sure.
It's this:

I think i'll just buy that fan to be safe.
I could do that but I hardly have any software on there. I only installed windows on it not that long ago. Plus it only started to happen when I moved the PC to a different location. Ultimately I'm going to get a sound card anyway in the next few weeks so it's not that big of a deal.
And after more testing it seems like it's only HD video on youtube that I'm having an issue with, netflix HD is flawless.
Well it's just an easy way to rule out any coincidental software issues. Ultimately it's up to you but if you're going to assume that it's not a software problem without testing then it has to be a motherboard issue.
Make sure the audio card has good shielding.
As far as youtube goes make sure flash, your browser, and your graphics drivers are up to date. Try different browsers. Maybe something is wrong with the codec? This problem has to be a software issue for sure.
Is there really some kind of software that could actually have such a physical effect?
Yeah I'm going to look into the youtube issue some more now I know it's just youtube, I could have sworn I tested it with some HD footage away from youtube but I guess I didn't.

I'm actually experiencing some interference too, and was considering buying a sound card, partly to remedy that. However, I'm wondering if
this card has good enough shielding. It's listed as just "EMI", which makes little sense to me as it stands for "electromagnetic interference"... And isn't really descriptive of the shielding.
The more expensive model has copper plating, but it would be really overkill for me to get it since I'm not that much of an audiophile anyway. So, would the cheaper one help me?

Yes. Everything you see and hear on your computer is produced by software.

Elaborate.

They will never list the details of the shielding. "EMI shielding" just means that the shield is designed to impede EMI. In this case the EMI shield is a thin sheet of aluminum bent around the DAC. Which is what they usually do because it's cheap and effective.

Impossible to say with absolute certainty. Too many variables to consider. For starters what is your audio setup like (cabling, outputs, inputs, etc.)?
NV putting words in my mouth. Lol.
@NV: Well, sometimes, when scrolling a page in firefox, I can hear faint static in my headphones. When playing games or watching videos, this isn't a problem, as the sound from whatever I'm doing completely covers the static (in fact, I have no reliable way of knowing if it even is there at all - I can only assume).
My setup is... messy to say the least, and definitely not good for sound quality. =P It might be part of the problem now that I think of it. Basically, I have an audio cable going from my mobo's sound output into my monitor, which has in-built speakers; and then I have my headphones plugged into my monitor's sound output, which makes it easy to unplug them when needed without having to get behind my PC (and without wires trailing from my front panel). Sometimes, I want to use a different pair of headphones, which I then plug into the front panel.
If I do get that card, as I probably will, I'm most likely gonna change that.

Oh fuck.....
Been a long time since I've done that.
teh_speleegn_polease Wrote:Well, sometimes, when scrolling a page in firefox, I can hear faint static in my headphones.
Just when scrolling or does it happen when idle?

Well background static in movies usually can't be distinguished but it does make everything sound less clear. You might have trouble telling what people are saying for example because your brain is combining the static soundwaves with their voice.

[screams internally]
Hopefully you know by now that integrated monitor speakers are the worst quality speakers on the planet. Due to space restrictions they're often forced to use 1" paper cone drivers with very basic amplifier ciruits. On top of being exposed to high EMI from high power video and audio circuits being crammed right next to each other.
Does your monitor have an audio volume control? If so try raising your monitor volume and lowering your PC volume. Then vice versa. Tell me which one sounds better and that will help us pinpoint the source of the interference.
Do you notice a difference plugging the headphones directly into the front panel?
There are so many potential sources of EMI in a computer that is can be tricky to track down the source. What type of video and audio cables do you use? The cables themselves are often a source of significant EMI.
@NV:
It only happens when scrolling. Most of the time it's so faint that even typing would cover it completely (not that I often type while scrolling, lol).
And yes, I know the speakers are bad, but the only time I ever ever use them it to play Mario Party 8 and such with my friend when he comes over. Anything better than putting the headphones in the middle of the desk and cranking up the volume to max is fine for us.
As for the rest... I use a random audio cable that came with my monitor, same with DVI. I don't remember noticing the static when using the front panel, but then again I don't use it often and I may just not have noticed.
I've actually already ordered the sound card, together with some speakers and a new monitor. Thanks for the help though.
teh_speleegn_polease Wrote:As for the rest... I use a random audio cable that came with my monitor
I'm going to assume unshielded TRS.

I didn't do anything. *shrugs* Sure why not, your welcome.
