I just installed my new 7950, now my PC won't boot. I also pulled my PSU out and sleeved all the wires. Here is what I did in detail
-AMD965 Black
-MSI G46 mobo
-Sapphire 7950
-750w PSU
-Corsair Vengeance 16gb ddr3
Pulled PSU out and sleeved 20pin and 4pin for mobo, sleeved the 2 6pins for the GPU, and sleeved the molex 4pins for my 5.25. When I did the mobo harnesses, I did them one wire at a time so I would make absolutely sure I didn't put a wire in the wrong spot. I've checked to make sure every pin is closed tight enough to make a solid connection when plugged into the mobo.
Put the PSU back in and installed the 7950 and plugged everything in. I've quadruple checked that everything is connected to the mobo, and I can't figure out for the life of me whats wrong.
I plug the power into the PSU and flip the switch on. When I press the power switch on my case the GPU fans make about one rotation and shut off. No lights anywhere and no beeping.
I pulled the memory out and replaced it with some older corsair to see if that went bad, same issue. I also swapped in my 6770 to see if the 7950 was the problem, exact same thing.
I'm thinking its narrowed down to either the mobo or the psu. If there is a way to confirm either of these are bad, please let me know. I'm running out of aspirin from my head being stuffed inside this case all night.
