buzzing sound and a little video drag

I have formatted my HD ,,thinking a possible conflict with drivers..the buzzing started again even before installing drivers..I replaced the sound card..back to the on board card..no driver up grade..the MB is asus p8p67..it has been doing this for 6 months,,I have had the pc for 2 years ,,2 weeks and 3 days..I am very unhappy.Is there a way to check the motherboard on line?

This is a common problem, and you have 2 issues.

1 A buzzing sound.
2 Video lag.

You could look at your codecs.
Have you got any power cables crossing and speaker cables.
Does this happen when you are using earphones(Try using earphones, if you have no buzzing this will answer alot of questions)

If the "buzzing sound" is in the speakers, it could be a "ground loop" hum problem. What all do you have connected to the PC? (other than the keyboard/mouse)?

I have 2 power strips near the pc .one is big..,in the PC a small router connecting to 2 other pc's, 2 monitors,(one is a visio TV that I use as a monitor).2 printers, a wireless mouse and keyboard,

You have given me hope..I have been really stressed that it might be the motherboard..
thanks

Have you tried using headphones?

Any of the other devices could be causing a "ground loop" hum. Unplug one at a time from the AC power line and see if it changes. It could even be more than one device.

Ground loop hums are caused by a "difference in potential" of the AC power grounds. Those of us that are musicians come across this frequently with connecting various effects, two amps, etc. This can happen even if the two devices are plugged into the same AC power source (e.g. the same power strip).

If you are getting buzzing from the headphones as well as the speakers then I dont think it is a ground loop problem, can you borrow a USB sound card from anyone to try? This is purley for diag.

Do you have a mic that is always on? this could cause the problem.
