Hi, I just built a gaming pc a couple days ago, and have been downloading games for the past couple of days. I started oblivion and my computer started squealing, and when i exited or minimized oblivion it would stop squealing. I tried playing halo, and the same thing occurred, it would stop squealing when i minimized or exited the game. One of the fans in the top of my case does not work, if that is the issue... Someone please help!! 🙁
