Hi there everybody! So I recently finished building my new Sandy Bridge rig. I have an Asrock Extreme4 Gen 3, with a XFX 5850, a 2500k, and an Antec Truepower New 650w. Everything is working perfectly except for one thing. It emits a low frequency hum/whine during use. It doesn't increase during certain activities and it doesn't decrease. It stays at a constant level of whine that's so annoying, it's burrowing a hole in my ear. This has been going on for around 2 weeks ever since I got it. ARGH! Is there anyway to stop this noise? I read somewhere that was an option you could toggle in the BIOS that could help, but I'm not sure how much truth there is to that. Any advice will do, this is really driving me MENTAL! Thanks for reading!
