I recently installed the Z97 Extreme4, replacing my old P5k board.
I hear a hum when I plug my microphone in. The hum goes away when I touch the case of my computer.
The hum is louder when plugged into an UNGROUNDED plug power. - So much so that i'm unable to record with mic.'
There is no hum at all when mic is NOT plugged in.
Firstly is this hum damaging to the motherboard?
Clearly there is some electricity going into my case - and I'm not sure if that is normal or not - I'm not feeling too happy about it though ;)
Secondly, I'm wondering if this is related to bad assembly on my part. Perhaps anything to do with the "back plugs"? (I mean the small plugs; that the screws that fasten the motherboard to the case go into)
- Could I have 'missed' one of those as I switched motherboards? Or wouldn't this matter? Are these the only 'metal connections' between MB and case? )
Thirdly, does anyone have a solution or has encountered this before?
Thanks!
