Set up:
* Dual M-Audio Delta 1010's
* Soundtracks MIDI PC24 Desk
* Alesis MK2 Monitors plugged directly in to my first M-Audio Delta 1010
* 3.0Ghz Pentium IV Prescot (NOT Duel Core) with 1GB RAM, 300GB HDD, DVDRAM Drive, Asus x800 Graphics Card with 2 monitors.
Issue:
About 6 months ago I started to hear a rather lage buzz when I booted my PC up coming from my monitors. It faded away by the time the PC had booted in to windows.
It's been getting gradually worse, and it got to a point where it buzzed VERY loudly for an hour or more after I booted up, then went away. Now it's buzzing loudly for an hour or more, then getting quieter and sometimes dissapearing entirely - but ALWAYS comes back with force at some point.
Troubleshooting:
I initially thought it was my graphics card fan interfering with the sound cards, so replaced that - to no avail. Then I replaced the PSU as that was making a racket too... wasn't that either.
I eventually got the stomach (I hate having to get dirty with my PC these days, I just can't be bothered with them ) to open up my PC and diagnose the problem - removed everything but the power supply, and even unhooked the Motherboard from the case to avoid the doubt that there may be a shorting issue somewhere. The buzz was still there.
However - the buzz only happens when the PCI cards for the Delta 1010's are plugged in to my PC - bearing in mind that the Delta 1010s are powered seperately and the monitors are plugged directly in to the outputs on the soundcard. Which suggests to me that it's nothing to do with the sound card and is in fact my motherboard / CPU? I refuse to believe that a second PSU could create the same issues?
I tried just having one sound card running, I tried swapping the PCI cards over, tried plugging the monitors in to all the different inputs on the sound card, and even tried the second sound card on its own. The buzz was STILL there.
Another thing worth mentioning is that the noise happens straight from POST - so it would more likely be a hardware problem than a software / driver issue.
When my CPU gets a little more active, the buzzing seems to get worse... though it's intermittant.
Does anyone have any suggestions / experience with similar problems? I'm going to try to put the soundcards in another PC on Thursday to see if I can rule them out, but I'm utterly stumped.
