Okay, this is a very odd problem. What happens exactly is that at what seems a random point of time, usually long after the computer's been turned on though, a very loud buzzing and static-y sound will start playing from my speakers (or headphones if they're plugged in). This goes on for about 5 seconds, and then all audio cuts. Oddly enough, if I even try to play a sound (say I press Play on a song in Winamp) it won't even play the song at all, almost as though it knows the sound won't work. If I let a video play, there's a big lag time before it starts, and then it plays, but without sound. If I wait long enough, usually about 5 minutes, the sound comes back. I at first thought it might be my speakers, considering they're almost 6 years old, but when I noticed this would happen to my headphones too, I figured it was the sound card. My sound card is a Creative SB X-Fi. Any other information that you need, please just tell me. I hope this problem isn't as odd and uncommon as I think it is =P All help is greatly appreciated! Thanks.
