FPS drop because of sound card / sound card drivers?

[radu]

I've recently upgraded my os to windows 7, and noticed a significant
fps drop in all games I've installed. The problem seems to come from the sound card.
I've disabled it in device manager and I gained a steady 15-20 more in most of the applications.
Any idea what to do? Is it a driver issue or something? I got an Athlon 64x2 4600+, Asus M2N mainboard,
2 gigs of ram, Gainward 8800GS video card, Sound Blaster Live 24bit soundcard.

Drivers are downloaded from creative.

Have you updated your audio drivers since the new installation? Perhaps a run down of what you have done may yield better answers for you?

Yeah, I tried updating and even reinstalled windows 7. Same problem. I wanted to reenable the onboard soundcard from bios, see how it works, but it's password protected and, well, I forgot the password
