zholtberg Posted October 28, 2010 Share Posted October 28, 2010 Well, I'm pretty sure the source of the sound is coming from the PSU, but who's to blame? I have a 750TX power supply and an EVGA GTX 470 and the PC is all new parts. The noise is really high pitched and varies in tone. Faded away for a while and the next day came back even louder. I can manipulate the pitch of the squeal by flipping menus or scrolling back and forth on webpages. Unlike many of the descriptions of coil whine I've seen, mine happens all the time - not just 3D games. Even in the BIOS screens. I proceeded to take the video card out and powered it up - no squeal. I put it back in and rebooted and still silent until a couple minutes later. Right now the noise is there but very much reduced. Any ideas which component is really at fault? I don't have another video card to try to determine if it's the video card, or if it's the PSU failing to provide enough power. The noise is bare-able at the moment, but I'm worried it will just come back. Thanks! Link to comment Share on other sites More sharing options...
