Interesting problem! i7-4790k

[seeme]

I wanted to upgrade my cpu from Intel Pentium G3220 to an i7-4790k. When I install the new cpu in my computer it won't boot. There is no signal to the monitor and no power to keyboard/mouse. When i reinstall the old cpu everything works normally. I have upgraded to the latest BIOS and can not seem to isolate the problem. Does anyone have suggastions to where the problem might lay? I know the i7 is overkill, but it is an ongoing upgrade.

 

Specs:

Corsair CX 500W PSU - ASUS B85M-G, Socket-1150 - Crucial DDR3 BallistiX Sport 1600MHz 4GB - ZOTAC GeForce GTX 750 1GB PhysX CUDA -

Windows 8.1

if you overclocked the 3220 you may need to reset the bios.

nvrmind say your specs.

 

Edit again: what revison is your bios, it may need to be updated. altho personally I would get a z97 for that cpu.
