SDN Members don't see this ad. About the ads. I have a laptop running Windows XP. It often makes a random "woosh woosh". I have all sounds turned off under system sounds. The same issue is discussed in these threads: http://forums.whirlpool.net.au/forum-replies-archive.cfm/1066013.html http://forums.anandtech.com/messageview.aspx?catid=27&threadid=2255139 The audio recording (WAV file) of the noise is here: http://www.2shared.com/file/4056355/3d77750b/strangewhoosh.html It's a Dell laptop. I had an older Dell laptop which also made this sound at random. The only common programs that are running on these laptops are McAfee Virus Scan, Widcomm Bluetooth Stack, Intel Proset Wireless utility, Zonealarm, Firefox (with some extensions), all on Windows XP SP2. There are some other processes running too, but I don't think they make this sound. Does anyone know what program or event is causing this noise? Please help, it's driving me nuts.
