cear Posted May 1, 2012 Report Share Posted May 1, 2012 I recently bought new studio monitors (Yamaha's HSM80's) and a new usb audio interface (Focusrite Scralett 2i2). When I hooked it all up on my desktop pc and turned on the speakers I could hear a sharp noise representing CPU movement (I literally hear the CPU working). I hooked the monitors on to a cheap laptop, bam no noise at all (so it's definitely not the speakers or the audio interface). Tried it on another desktop pc as well, I got slight noises but not as big of an annoyance. We tried about everything to eliminate that the problem was the motherboard in combo with the cpu or one on on their own (I'm guessing probably the mobo). I disconnected all other usb devices, we changed video cards, we even changed the power supply unit of the PC. The noise was still there. Changing CPU would've been a bit too much of a hassle. I need to buy a new cpu either way if I need to switch motherboard, since the motherboards socket got really expensive (Socket 1366).. Buying new CPU+Mobo would be smarter. My question is, should I just buy another motherboard + cpu (I'm able to do so) or is there another solution? Could I be able to run into the same problems with a new motherboard (this one I have now is +2 years old, there might be some electronics that got fucked over the years or so..) I'm pretty much an electronic noob so I'm running pretty much out of ideas here.. Don't get really great answers from the net, people keep referring to eliminators. But they look hoax'y.. Anyone who has had a similar problem here (probably yes..)? A quick & easy solution with certainty of success? thanx Thanks Haha Confused Sad Facepalm Burger Farnsworth Big Brain Like × Quote Hide cear's signature Hide all signatures Я твой слуга, Я твой работник Link to comment https://forum.watmm.com/topic/73478-mobo-cpu-noise-problems/ Share on other sites More sharing options...
AAAAh Posted May 1, 2012 Report Share Posted May 1, 2012 I have experienced that with an onboard soundcard, never with usb though. Using a pci USB card might help, and would be cheaper and easier that a complete refit.

Guest Drahken Posted May 1, 2012 Report Share Posted May 1, 2012 You could try increasing the spread spectrum if your BIOS has that option. Quote Link to comment https://forum.watmm.com/topic/73478-mobo-cpu-noise-problems/#findComment-1809698 Share on other sites More sharing options...
mcbpete Posted May 1, 2012 Report Share Posted May 1, 2012 Possibly an electrical grounding problem. Was the laptop running on batteries when you tried it - if so that supports the theory that your mains supply may be leaky.

My BIOS had it just on Auto and I set it on Enabled now and the noise is remarkably more silent! It's still there but not as bothersome (or else it's already habituating in my ears, lol.). I am looking for a complete silent solution though, but this is good. On 5/1/2012 at 8:07 PM, mcbpete said: Possibly an electrical grounding problem.

I literally switched its cable with the cable of the desktop pc, same with the other desktop.

Try a different outlet for the two and it may help. I had this problem in my old house, it had really old wiring (only two-pronged plugs, none of them were 3-prong grounded they were so old) and plugging the monitors into a different outlet didn't fix it completely (I believe because they were still on the same circuit), but made it much less noticeable.

Guest Drahken Posted May 1, 2012 Report Share Posted May 1, 2012 If spread spectrum helped than it is most likely your motherboard/cpu combo producing EMI. You could try installing a PCI usb card but if that doesn't help your best bet is to upgrade. When you go to upgrade do some research on audio-specific builds to get an idea of what components are least likely to have this issue.

audio Posted May 5, 2012 Report Share Posted May 5, 2012 Hey there, I had this exact same problem with my M-Audio Firewire Solo and Mackie MR8's. Turns out it was a problem with my grounding. I bought this this fucking beauty to and plugged my interface into it, and then the Hum-X into my surge protector. Problem solved! Hope it works out for you.

foresense Posted May 6, 2012 Report Share Posted May 6, 2012 I can't change spread spectrum, only turn it on or off? turning off C1E support in my mobo helped quite a bit.
