I have a problem that I have been fighting for the past couple of weeks that I cannot figure out. My speakers started humming when I play any game and the hum changes with whats on screen. I found that I had a ground loop and fixed it but the noise continued. I tried a new SoundblasterX AE-5 and the noise is still there. I bought a Evga 1080Ti FTW card and the noise is still there. I tried onboard sound on my Asus Strix X-99, same sound. I tried optical on the Soundblaster and motherboard and the hum is still there. I bought a new shielded displayport cable same hum. I run my speakers through a Marantz receiver with every console available now hooked up to the receiver I get no noise with the consoles, only the PC. The next thing im going to try is a new power supply right now I have a EVGA supernova 1000p. One thing I noticed that seemed odd was when I hooked up the molex connector to the Soundblaster card the computer wouldnt power on, unhook the molex and it would power on. Does anybody have any other suggestions cause this is driving me crazy.
