Im having a strange problem with my computer. Whenever sound is playing through a game or mp3s whatever every once in a while my computer will freeze and the speakers make a high pitched screaming noise, and after about 30-234.2 seconds it will kick back in and be normal again. also it has a tendancy to happen at about 12am central time thats why i think its a trojan. Well im running xppro and i run virus scan every week so its not a virus or trojan im sure.. heh i always assume the worst.. its probably my sound card drivers. anyways thanks for the help. It was just strange because this never has happened before.
