[Solved] Static/crackly audio. I dont know whats wrong anymore?

Alright, well to begin with, while listening to music or really doing something that produces audio on my computer the sound will occasionally start getting very static or crackly for no reason at all. Here are my specs:

Creative SB X-FI Titanium Fatal1ty driver v. 6.0.1.1347
Logitech z-5500
Windows 7 32-bit
MB: GA-MA785GM-US2H BIOS V. F7
CPU: AMD Phenom II X4 955 Black Edition

Now, I dont think the speakers are at fault because while gaming on my PS3 (optical cables) with them, the sound doesn't mess up at all.

Heres what i tried to do for troubleshooting:
Unplugged optical cable from PS3 and plugged into Fatal1ty SB= After a while the sound still got static.
Instead of plugging the 3.5mm audio cables into the Fatal1ty SB, i plugged them into the on-board one= Still get static
Plugged optical cable into on-board SB= Still get static.

As you can see, everything seems ruled out! Please help in any way that you can because I really want my sound back to the way it used to be.

I suspect the Creative card. Remove the drivers, remove the card, and the issue will most likely go away entirely. Since Creative is always the most likely suspect, lets eliminate them first.

Alright, thanks for all the help. Ill install the drivers given by mosox and if that doesn't work thenill just go down the list by removing the card, rolling back drivers, etc.

Ok with al the maybe's and if's and but's... the bottom line is actually that the static in the speakers can be caused due to very few reasons.....
Firstly and the most common one is a FAN, any of the fans on the inside can end up causing such sounds to come from the speakers,
Secondly , a loose contact ..., badly placed card, too close to a fan...
and thirdly the 16Bit and 24Bit headache.....

So you can check out the three options and let us know the results....
