Ok. I have the asu a7n8x motherboeard.I dont know if this motherboard is common for bad sound but I have my computer hooked to my home stereo system. When I turn it up nomatter if im playing any music or a game on my computer it ALWAYS has a deep hum. Basicllly constant bass. I have gotten my rca's away from high current and all that. Anyway I know its coming from my computer so what could I do to fix this crappy sound? There is no 1 fam or 1 thing in my computer interrupting the signal. Even if I cant get rid of it completely what can i do to deaden it. Please Help. Thanks

make sure the microphone is muted make sure the stereo is grounded make sure you are not plugged into the phono plug on the stereo - use only the aux or C or tape plug if you want to know if its coming from your computer, unplug the stereo and plug the speaker out line into conventional PC speakers.

Here let me make myself clear the noise is coming from in my computer. It has nothing to do with my stereo. Anyone have any suggestions on what problem i might have somewhere IN MY COMPUTER. Thanks

Hum that you end up hearing in the computer sound can come from anything connected to your computer, or anything nearby. The frequency of it is that of the AC you are plugged into - 60cps(hz)or 50 cps(hz). I have the same problem, mildly so - I can hear it in my amplified speakers when the computer is off - I haven't pinned down where it comes from - probably the speaker power pack. You should get the least hum if the volume on the computer is lower, and on the stereo is higher. Adjust the level mostly on the stereo. If you have both speaker out and line out jacks for the computer sound, use line out. Some sound that does not have separate line out has settings somewhere where you can select the output type - speaker (low impedence), line out or headphone (higher impedence), etc. Choose the latter. What do you have the computer sound plugged into on the stereo? You could try plugging into a different set of input jacks. Don't plug into phono if you have that - very likely to pick up hum, very likely to give you distorted sound (impedence is too high, and/or amplification is too much). Keep the cover on your computer case. The case is designed to block sources of radio frequency interference. Common culprits are the power packs that power devices connected to your computer, including your printer, which may have a separate or integrated one - try unplugging them all to see if the hum goes away. If you have both the connection to your stereo and amplified speakers connected to the computer, hum can come from the power pack for the speakers. If it does go away, plug them in one at a time to pin down which power pack is the problem. The only cure for a noisy power pack is a better one, unless you want to mess with adding a noise filter between it and what it powers, which may not work. You could also try unplugging the AC to everything connected to the computer other than the power supply. Assuming your computer is plugged into a grounded AC connection like it should be, it's not supposed to come from your AC power source, but that's possible. e.g. a bad ballast in flourescent lights on the same circuit can cause hum - try turning off the lights in that case. Try unplugging or turning off everything else on the same AC circuit. You could try running an extension to an AC circuit nearby that is not on the same circuit (on your power panel)as you are now using. You can also pick up hum between your computer and your stereo. The more sheilding those cables have the better - e.g. ones meant for VCR's usually have good shielding. Usually the thicker the cable, the better. Thin cables meant for headphones, etc., may not have enough shielding. Try better cables. You could also try running a ground wire from a screw on your computer case that is grounded to a grounded screw (or a ground terminal if it has that) on your stereo.

Well thanks for the advice mike my power supply is one of the best they make(Vantec ION 400b.I mean I know the sounds are coming from my computer with the fans and all that i was just wondering if there is a way to deaden it or maybe if my mobo isnt grounded good or something like that i have tried pretty much eveything but thanks for the help.

turn the wav volume down to about 80% i had a problem with the sound crackling on an different motherboard nothing to do with my stereo, i know its a different sound problem but it could solve it.

I didn't say anything about your computer power supply. It is very rare for a PS to cause hum in your computer sound, unless it is defective, as in its capacitors are leaking and inoperative. And you don't get hum from a DC powered fan, like that inside a computer case. Power packs - as in the plastic rectangular modules, either right on the AC plug end of the cord, or somewhere between the AC plug and the device they power, or a modular pack built into but clearly visible as a separate unit, on devices such as some printers, that supply DC power to a device that connects to your computer. These often have minimal filtering to block hum, they produce both DC and a small amount of AC voltage, and depending on how much AC they produce and the filtering capabilities of the device they power, it is common to have some of that 50 or 60 cps hum leak through, and that can end up showing up in your computer sound. Another suggestion - better surge suppressor power bars have EMI (Electro Magnetic Interference) filtering built into them - some have several isolated banks of them (e.g. TrippLite Isobar)- if you have, or get, one of those, you could plug all the devices you can that connect to the computer into the surge suppresor power bar and that may kill the hum.
