so I set it all up, configured the waterloop (for G80).
ok all leads are connected on the prommy, power button pressed.
prommy goes down to -35C. then PSU comes on, fans spin, DDC pumps away but nothing else happens. no keybaord backlights, no beeps, nothing.

this is on a P5B-D with QX6700 and 8800GTX. they all worked together fine when the CPU was watercooled and GTX was aircooled.

hope I havent killed something somehow and if I have I hope its the GTX.
I dont have another CPU or a HSF or another PCI-E gfx card to try.
