Hey guys I got a new question for you, hope you can help out. I just recently today noticed a high pitched noise coming from my computer. I think I've narrowed it down to the PSU making a coil whine. It sounds like a similar problem someone else has below.... http://www.youtube.com/watch?feature=player_embedded&v=C4d23F2jehQ Basically anytime I load up a game and the FPS is up high because of v-sync turned off, its really noticeable. It changes pitch as FPS goes up or down. I think I've come to understand that the different voltages give off different audibles and what I'm hearing could be normal? I've never noticed because I game with a headset and the GPU fan speed drowns it out. But I'm a little concerned that it could be an issue. Could the PSU be going bad? Is there any kind of damage to any other components if this happens? Such as GPU or Motherboard... I hate to replace the PSU because I've read others have replaced it and the new one does the same thing. It has something to do with the amount of voltage that the GPU is pulling from the PSU but I dont want it to cause damage....Hopefully you can help out. Looking forward to hearing back from you guys. Thanks!
