Possible static pressure issue on my cpu, gpu or motherboard?

[xaviermartinez45]

This is my first build and i was installing my corsair h100i into my PC. The install went well but when i booted up the pc and entered the bios, the computer turned off randomly. I have a asus sabertooth 990fx r2.0 and my cpu is a amd fx-8350. The motherboard no longer lets me access bios. I am afraid it could also be my graphics card because i get a black screen when my pc boots. Fans are running and the cpu led light stays lit red. My gpu is a asus 7870hd. I have no idea what to do, please help. I hope the problem is smaller than what i think.

Hi, Have you applied thermal paste when installing the cooler?
The computer turning off randomly could have been related to overheating.
Try installing the stock CPU fan and see if still the same.
Clean the old thermal paste and apply new one. Check on Youtube for how to.

the h100 already has thermal paste on it if its the same as the h80

did you tighten the block down in an x pattern?

ie screw 1 then 3 then 2 then 4

this is to make sure it goes down flat and evenly

also did you connect the pump power connector?
