Hi all,

first up, computer specs are,

Intel i5 6600

ASrock Fatality micro ITX motherboard

GTX 1070 SC EVGA graphic card

16gb DDR4 2400MHZ Kingston hyperfury ram

Crucial 500gb M.2 harddrive

XFT XT 500 watt power supply.

Having completed the build this morning I connected the computer to the monitor and switched it on. Initially all looking good, fans spinning on case and CPU cooler, lights turned on on the graphics card etc. However, the monitor keeps saying 'no signal' (monitor connected to back of GPU not motherboard).

Things I have tried...

booting up from a different monitor

Changing cables

booting with GPU removed

booting with RAM removed

Also, whether this makes a difference or not but the GPU will fire up initially (fans spinning) then the fans will stop after about 30 seconds - however lights stay switched on GPU.

I'm not getting any noises from computer either.

Any thoughts?

for debugging use one ram stick and onboard video. start with the face slaping stuff a lot of people miss. make sure the 4/8 pin cpu power connector is filled and you used a cpu and not video power cable. make sure the mb standoffs are used and the mb not tuching the mb tray or io shield. if they look fine pull the mb see if she post sitting on top of the mb box with just the power supply plugged in. if there no joy try another power supply to see if it the power supply or mb/cpu. if with a test power supply there no post make sure the cpu is locked in and there no bent pins under the cpu.
