Several times a day my microphone is recording noise.
It usually records two short sounds then another two. Those 4 signals are something about 10kHz, also other noise happens around that time. The noise lasts for a few seconds to a minute. Then problem disappears for several minutes or hours.
The microphone is a part of headphones from Sennheiser. The only suspicious thing in it is a common zero/ground wire of mic and headphones - it has a common 3-wire microjack. Both microphone and headphones are connected (by two minijack sockets) at the back of my PC to a soundcard on the P5B-VM motherboard.
PSU (a water coolled FEEL) is another suspect. But I don't understand how PSU could generate electric noise only sometimes.
It is impossible to connect MIC to front panel, it never worked.
I disconnected HDD and CD/DVD, there is no WiFi in that PC.
What is the cause of noise? Is it PSU, soundcard on motherboard, some radio communication like neighbour's mobile phone, windows 7 virtual memory on SSD, U-F-nOise ?
I can afford to replace _one_ faulty component, but not the entire PC.
Can I be sure that BeQuiet Dark Power Pro 550W will solve this problem?
