Prob with X-fi Music edit

Question

I Have had the Sound card for, i would say 2 weeks or so. I have a Pent 4 2.8, gig of ram, 350 watt Power supply, 20gig HD and a Radeon 9800 pro. I started noticeing probs in BF2 about 3 days after i got the card. I started to hear what other people were hearing as if my Right speakers were connected to his game. I would hear everything he would. I then started to hear skipping when i would start to shoot or sounds wouldnt play at all. THen this is what got me mad. At any randome time after i played BF2, During, or anytime really. My computer would just restart randomly. Like it goes to black screen and turns off. Another prob is when i am playing any game, i talk on ventrilo, it wont let me talk at all. On ventrilo or in game useing my mic. I have tried to reformat my HD, that didnt work, put the sound card in a differnt PCI slot. That didnt work. Reinstalled Drivers, that didnt work. THis all started after i got the Sound card to. So there for I have come to think of it that my power suplly isnt good enough, I dont know really what my computer/ sound card needs. Or that the sound card is faulty. I need help on makeing a dicession. Send the card in for a new one. Or replace the Powersupply or check the computer. Or if someone could give me some help, would be much appricated.
P.S I have the logitech Z-5500 speaker system.

Do you have Windows XP? If so, do the following:
. Right-click on My Computer and select Properties from the pop-up menu.
2. In the window that appears, click on the Advanced tab and then click on the Settings button under the Startup and Recovery heading (at the bottom).
3. Under the Systen Failure heading, click on the checkbox that says "Automaticall Restart" so that the box is UNchecked. Click Apply and then OK.
4. If you are asked to restart your computer, save whatever you're doing and restart.
5. Play Battlefield 2 until your computer crashes. You should now see a blue screen that says STOP: 00000Cx0 or something like that at the top. Write down the error message, the numbers next to the STOP:, and any files that are listed at the bottom.
Chances are those restarts are really STOP Errors, but Windows XP is set to not show them by default. It'll restart instead. Those messages can be very helpful in determining where the problem is. Write down what you can and then reply back here with what it says.
