I have a Xonar DX and, some reason it makes a high pitched noise, it's low in volume but once I hear it I cant unhear it, it drives me crazy because of how subtle it is. (it becomes more obvious if i use my IEM)
However, it seems that it only makes on my PC, since I asked friend, who seems to be pretty sensitive to these kind o noises to test in his PC.
I have tried chaging PSU, Graphics card, RAM,sound card's power cable, power socket, turning off everything in the room.
The only things I have not tried are chaging processor, motherboard, HDD, case.
My motherboards built-in sound card doesn't make this noise.
I have the feeling that it's most likely because of the motherboard, however, I want to wait a bit more before upgrading.
Do you guys have any solutions I may try?
Motherboard: Sabertooth 55i
Processor: i5 750 @3.8
RAM: 8GB DDR3 1600Mhz
PSU: Corsair TX850M
Graphics card: Gigabyte GTX760
Case: Nox VX
