Right, I have fitted an Abit AN8 ultra in my gigabyte aurora case with a x850 pro, and it wont start, 5vsb light is on on the mobo, but press the power switch and ..no fans nothing.
I read on the Abit forum of something similar happening to somebody in an older tower case, the switch voltage went to earth via the front panel circuit board and it wouldn't switch on (TBH the post wasn' very clear!)
The switch on my case is just two wires, so as far as I can see it cannot have any connection to a common earth.
My psu is an Aerocool2 (420 or 450 W ) and I have a vague recollection of mbm5 having a problem with it when I put it in due to the apparent lack of a "-5v". I asked on the forums then and recieved the reply that it wasn't a problem as my NF7-S didn't need one.
Is this correct and could this cause my "non starting" problem.
Please help! as I am already well beyond the limit of my knowledge and reaching the end of my patience!
(Sorry this is a bit "war & peace!)
