Hi.. i got a problem and I've been checking online to find a solution to this problem and I haven't been able to. There is a high pitch hum coming from my computer, and it also flows through my speakers so the higher the volume, the higher the high pitch sound gets.. and its giving me a headache. I unplugged the videocard/moniter and speakers yet the hum sound is still there. Even when i shut down my computer, I can still hear it, and when I unplug the cable from the power box to my motherboard the sound went away, also if i move the cords from that plug it stops/turns back on, so I'm figuring it has something to do with that but got no idea what to actually do, thank you.
