Motherboard lights up but won’t turn on and no video output

[Elegy]

I recently installed a h100i v2(replacing my 212 evo) and a new 3tb hard drive(adding to my current 1tb and 250gb ssd) and after I connected them, when I tryed to turned the computer on the motherboard lit up and all the fans turned on and gpu but the temp that appears on my motherboard when it’s booted didn’t light up and no video is projected onto my monitors when plugged into the motherboard hdmi or gpu.

Could it be because of a bent pin on the cpu socket?

perhaps u may  have tightened to cooler too tight try taking it off and having a look at the pins

Sometimes with bent pins you don't POST (it power cycles every 10 or so seconds), or it just stops turning on. If you're not power cycling then you might want to try the CPU fan thing up there, but to be sure you should clear your CMOS and see if you boot.

 

Also go back to the air cooler just to see if that'll boot up.
