Hey, I am sorry if I posted in the wrong section, I didn't know where to post. I just bought a new computer in April and I've been gaming on it about 20 hours a week since. Just recently I noticed a subtle high pitched hum ONLY WHEN I'M IN GAME. I can go to the main menu, and it will stop. I have well enough the minimum requirements to play the games I do, so it's not like I'm trying to overload my PC. Could this be a hard drive issue? Intel QC i7-3770 16gb DDR3 SDRAM Unfortunately I just found out I have a Seagate Barracuda 2TB SATA 6.0Gbs 64MB Cache 7200 RPM 3.5 Inch Desktop Hard Drive... which may be the problem? nVidia GeForce GTX650 2Gb Don't know PSU yet, sorry. Does this sound familiar to anyone? I have a 3 year warranty so whatever the problem is, I should be able to get fixed. I wanted to see if anyone might have an idea of what it could be. It's hard to tell where the noise is coming from. I'm guessing it's either the PSU or H/D.
