Just installed a new Motherboard and Processor, PC won't start up

[thejoker34]

Hi all, I recently installed a new ASUS Sabertooth Z97 Mark I Motherboard and a i5 4690k into my build. I have a gtx 780, and a 850 w PSU. Before I installed the new components, everything worked fine. Then I took out my stuff, installed everything, put back in the video card and RAM, and now nothing works. When I hit the power button to turn on the computer, nothing happens. Their is a single green light on the motherboard, right above where you connect the power switch, and reset switch.
I made sure that I had the 24 plug and 8 prong CPU plug pushed in all the way. I am really clueless. Is something fried? Did I just forget to do something? Any help would be appreciated!

Hi, Try starting the board by shorting with a screwdriver or similar the 2 pins on the motherboard corresponding to the power button, to rule out a switch issue.

I used a screwdriver, and nothing happened

Then it might be a power supply issue. Try the paperclip test. Connect a fan to a molex on the PSU and see if spinning:

Power supply is working,

Try testing the board outside the case, only CPU and CPU fan installed, 24 and 8 pin cables connected. If still no fan spinning, then it might be a board issue.
