However, now it sometimes fails on boot and there is this annoying humming sound that is so loud it even drowns out the sound of my case fans. Seeing as I have an Antec 900 case, you can imagine that this hum is pretty loud. Does anyone know a reason for this. I was thinking that it might have something to do with the power supply? This might also explain why it fails on boot!

Can you identify the source of the hum? You listed everything but the PSU.
My power supply is a OCZ GameXStream but I cant remember whether it is 600w or 700w :s I think it is 600w
Its hard to identify the source of the hum, but I think it is coming from my primary HDD. I have heard that a stethoscope is a good way of isolating noise?
