I just built my PC with purchased, all-new components. As soon as I put it all together, and turned it on, my graphics card (GTX 660 ti 2GB) was making this metallic whining noise. It's been there since day 1. When you boot up, the sound eventually goes away in about 5-10 minutes, but if you power down & up again, the sound returns.
I've tried graphics intensive programs like Adobe Premiere and DaVinci Resolve and the GPU works fine, quiet. It's just this sound on the first 5-10 minutes of start up. I'm wondering how serious this issue is and whether I should RMA this card for a new one.
