PC won't post

[Brandoncowen]

Hey guys,

I just recently built a new PC with a Asus z270e motherboard and an Intel i7 7700k processor. After I built it, I booted everything up and it posted and I loaded in Windows 10. After installing all the updates and drivers, I rebooted the PC and went to overclock my CPU. I do have liquid cooling. After I saved the BIOS settings for the overclock it froze. After 2 hours of a frozen screen I turned it off and rebooted it. Will not post. I cleared the CMOS with the jumper and still nothing. I then, replaced the motherboard and CPU and it still won't post. I've tried booting it up without any ram or gpu and it still doesn't post. Any ideas?

What is your power supply? Check all cables.
Do u remember which setting have you tweaked in bios? Does any lights come up on motherboard? Discribe what happens when u press power button

It powers on with LEDs active and fans active. Display has no signal. I changed my processor to 5.0GHZ and my DDR4 RAM to 3200mhz. I figured swapping the motherboard would fix that though. Maybe I should replace to RAM?
