HI all ive just built a new pc all new parts so far im running screen says no signal cant get it to boot to bios
gigabyte H110M-S2H motherboard
OCPC 16gb DDR4 ram 2133mhz
Intel core i7 6700k
ID-Cooling Frostflow 240L
480gb PNY SSD
Areocool Intergrator MOD XT 650watt psu
So basically ive installed everything checked it over and over again 2 4 pin to cpu, ram is seated correctly, 24+2 motherboard plug correctly plugged in correct amount of thermal paste on cpu made sure cpu is seated correctly quite hard to do wrong on these cpus. Only thing is ive got the 2 120mm fans that are on the radiator connected via a splitter to the cpu fan header and the 12v pump connected to the sys fan header i was worried if the pump was getting 12v and is there anyway i can check this? but if the cpu has power shouldnt it boot anyway?
Was going to try different ram
What i have done so far checked all plugs treid a vga cable treid a dvi cable and also a hdmi cable but nothing still no signal on screen. weird this is also i have a usb keyboard and mouse it will recongnise my mouse but not the keyboard? guessing due to drivers. Also tried another old type keyboard no luck. I have another 500watt psu laying around might be worth trying that?

Also to add im not using a dedicated gpu im using onboard!!!

Just checked on gigabyte website all supported ram is either 1.2volts theres one at 1.35volts but both mine are 1.5v could this be the problem the ram not getting enough power im assuming the just wouldnt run as good as they should
 
Unplug everything. To boot to bios all you need is the minimum amount of ram your motherboard supports, a working CPU and working video.
If your motherboard does not support 1.5v ram, your PC will not boot if that is what your ram requires. Read through the motherboard manual and see if it does. I am nearly positive your motherboard does not support 1.5v ram. If you are still in doubt, contact gigabyte tech support. They can give you a 100% answer very fast.

make sure the CPU fan is plugged in. Sometimes it will not post if its unplugged.
