My new PC's fans turn on (except the GPU) and the Keyboard lights flash but it doesn't post or show video on the screen.
CPU: AMD Phenom II x4 955 Black edition
MoBo: Biostar A780l3g
RAM: Kingston KHX 1600C9AD3K2
PSU: Corsair CX500 Builders series
GPU: Nvidia 9500gt
I don't think it's the RAM because the ram is proven to work with the Motherboard and I think the PSU is fine because the Fans spin. I know it's not the GPU because it works fine in my old PC. I tried re-seating the Ram and I know that the cpu power is plugged in so I think it's the CPU or the motherboard.
step 1. check to make sure all the mb, cpu and cpu cooling wires are connected
step 2. check to see if the video card is seated properly first take out and re-insert if that does not work take out the screw securing the the video card at the back and with your hand move the card to see if there is a loose connection in the psi connector box.
I'm sure all the wires are plugged in and I've tried integrated graphics with the same result however when I tried to start up with only one stick of ram in the slot furthest from the cpu the fan's start up then shut off within a few seconds even the case fan. Also i just remembered that I changed the ram from an Adata xpg series because it was giving no memory beeps and iv'e gone through most of the stuff on the list except breadboarding because i don't know what a good insulated surface would be.
