Winamp cuts in one computer but not in another

[Owaya]

Hello, I'm now testing my radio station and my idea is to use a computer especially for it, so it could be streaming 24/7, this computer is a laptop Dell pc with a Windows 7 and an intel centrino duo processor. The situation is that sometimes, after 30min streaming or a little more it cuts and start right away in 30 seconds since I have the automatic reconnection. I also tested this in my mac which I have Parallels installed, so I can use windows and Winamp, and here it never cuts, it can be streamed all day without a problem. So my conclusion is that is not about the connection or the router, it is about my pc computer

Do you have an idea why this could be happening?

Thanks
