Any one know why my computer would give off a humming sound when I scroll with the mouse wheel ? It only does it while the mouse wheel is being used once I stop scrolling it stops .It is corded. Also some times when my computer is just setting idle it will start to thumping or popping off and on for a few seconds . I tried to Google this but have not found anything that is really useful . thinks people DRW

Maybe the PSU. Have you tried listening to the inside when the side cover is off?

Is it because it doesn't know the words? ;)

Actually, I vote power supply as well . . .

But Dav I typed in the words for it :lol: . I pulled the side and heard nothing. started with each speaker ( 5.1) it is coming from bass speaker. seems like I read once about something to do with a ground on the computer itself. I'll see if I can find it again and post it. Thanks all DRW
OK update The ground was something about needing an earth ground and not just a ground from the electric wiring of the house. But I did not go out and drive a ground rod into the ground just to ground my computer :rofl: I did read in me speaker book about having my sub at least 3' away from the computer ( it was sitting right next to it) so I moved it and it seems to be gone hopefully for good .

There are special provisions in the NEC for so-called 60/120 volt technical equipment, mainly professional grade audio and video equipment supplied by so-called "balanced" 120 volt circuits. These cases generally use a grounding conductor which is "isolated" from the neutral conductor specifically for the purposes of noise and "hum" reduction.

That is odd; have you tried a different mouse to see if anything changes?

Hey Greg. Just by moving my bass speaker 3' away from my computer fixed it. It was right next to it and the manual said it should be a mim. of 3' from the computer. If all else fails read the instructions .
