Weird hissing/static from all audio output devices

[up-smash]

I get a weird static from my headset when I do anything on the desktop. And when I boot TF2 it gets even worse.

Suggestions?

Does your headset also have a Mic? Maybe want to check your sound options in the control panel to make sure that the mic boost is off if it does have one.

If it's not the mic, try to mute "CD AUDIO" or "CD MUSIC" from the windows mixer.

Also, if its a sound card, try to put it in another PCI slot.

my sound is on-board,

I tried the mic suggestion and I still get the static

I've messed around with every possible configuration... Copuld it possibly be something on the motherboard messing up that I have to repair?

Here is your problem.

I am 99.98% sure that installing a sound card will solve the issue. Onboard sound will indefinitely fail or cause hissing 99.97% of the time.
