I had an i5 4460 on an asus b85-pro gamer motherboard. I then bought an i7 4790 I installed it and when I tried to turn it on the computer starts but it doesnt POST it gets stuck on the DRAM LED (not sure what that means because my RAM has worked for 4 years?) To turn the computer off though I have to turn it off by the PSU, the power button doesn't turn it off. The computer stays on it doesnt go into boot loops but just no POST.

re-install the CPU again.  Inspect the socket for damage.
