Problem with SB titanium X-FI (NOISE)

Hi everyone, I've used this Forum to solve so many problems, and now I need help for a problem that i can't solve.

My Specs:
Intel Q9650
Motherboard XFX 790i Ultra Sli
Ram 4gb DDR3
2 x GTX280 XFX 640MHz 1gb (SLI)
PSU 1000W Enermax Galaxy DXX
Windows Vista Ultimate 64-bit

And... a "lovely" Creative Sound Blaster X-Fi Titanium Fatal1ty PCIe

I have the sound card instaled, and with the drivers that came with it.
But I've got a problem. With some games it makes a noise... very disgusting (the sound is similir to the one that makes a radio when it can't get the freqency... interference, it sounds more or less like chakchkachakchakchakchak....).

It happened with Call Of Duty World at War when i throw a gas greanade (but it happens since i upgrade the drivers and the creative console so i downgrade it to the version of the cd and the problem was solved).

With other games like Grand Theft Auto IV it happens more. If you're in a place with Smoke it sounds and at the menu when you select things...

I noticed that if i use a lower audo Quality (the minimum quality that i can use is 16bits 44100MHz), the noise is lower than if I use a better quality (the bigest quality 24 bits and 9600MHz makes a very loud noise). I tried to desactivate the Sound Blaster enhacements and everything but the noise continues.

I think that i have enough PSU, and the Integrated audio card works perfectly (well the quality ofcouse is lower but it never fails, so I'm using it)

Sorry about my english.

I hope you'll find a way to help me

Thanks !

It's possible that you just got a bad card, or one that is incompatible with the most current drivers. Personally I have not trusted creative products for a while. Razer (when you can find em), Diamond, and ASUS have some good sound cards, now anyway. Another thing may be interference with the speakers.

thats certainly a driver problem. What windows are you using? if the older drivers work perfectly dont upgrade them unless u MUST do it, creative is really bad at Drivers.

I bring bad news. Its most likely your MB. In the past Nvidia chip sets timed out to allow for GPU traffic. It created crashes and loud static on many Nvidia based MBs. Now with PCIE sound cards it makes near exactly the sound you speak of. This is a VERY common problem believe it or not. Other then that you should check to make sure your not putting your spdif output above the default. With vista it often conflicts with SB software and creates a his and or distortion.

edit: my problem is not sound card related

No they don't; I still have my onboard on with my Barracuda, no isses whatsoever...oh right...Creative...
