Xi-Fi Fatality doesn't b

Question

Here are my machine specs:
Motherboard: Intel DG35EC
Processor: Intel E8400
Graphic Card: evga Geforce 8800GTS
Sound Card Xi-Fi Fatality
OS: Windows XP SP2
The Problem:
After installing the drivers and rebooting everything worked fine. I heard
perfect surround sound. The next time I rebooted, however, there was no
sound. I went to the device manager and saw a yellow circle on the Xi-Fi
Drivers.
I rebooted again, there was still no sound, but the Xi-Fi Drivers had no
yellow circle this time.
A third reboot produced a loud static noise from the speakers.
Forth reboot everything worked fine.
These four symptoms happen randomly, each time I reboot I get one of the
above results. I have tried this with the newest drivers and the original
drivers from the CD. Both produce the same problem. I tried to format C: and
do a fresh install and that didn't help either. I also tried disabling the
on-board sound, both in the bios and in the device manager. That didn't
resolve anything.
I am suspecting that one of my hardware is conflicting with the Xi-Fi, but I
am not sure how to solve it. I even brought the computer to technician who
worked on it for a couple of days and haven't been able to solve it.
I would really appreciate any help and/or advice that anyone can offer, this
is very frustrating.

Answer 1

>_> The connections on the outward side of the tower are fine. It worked yesterday, and not today.
Last time it didn't work I rebooted and the sound worked for the rest of the day.
Now I get no sound out of it, the computer still registers it as being installed and working correctly, but there is no output.....
I think it looks grim, has anyone had any similar issues with anything like this?
