You measured 2.34A on 5V which is surprisingly high. Would be keen to see new load after these changes?

I'm going to build a CMP machine for another friend so I bought him a H55M-S2H for my experiment. I removed everything around the sound and network Chip, including regulators and transistors. See photo.
Current Consumption decreased by about 0.1A after such removal. Capacitor leakage current should also be taken into account. The 5V is now drawing 2.25A @96K. Sound quality slightly improved.
I can go on to remove the Jmicron IDE controller but I'd better stop here as this MB belong to my friend.

can you please point out where the chips are removed? hard to see.
Photo.
The optical output and an OP amp were removed.The CPU fan and System fan PS was cut off.

Two more chips, the DVI to HDMI Convertor chips for the DVI and HMDI output, were removed from the MB, with much hardship.
Not sure about any reduction in current consumption, that's not the point. The importance lies with the good improvement in SQ brought about by the risky but worthwhile surgical operation. As you can image, two noisy video chips were severed.
The last thing left, I belive, are a regulator and the Jmicron368 IDE controller. See pix below.
