Hello, 
To begin with my specs. 
PSU: Coolermaster m700 Silent pro
CPU: Intel i7 2600 core
RAM: 10 GB DDR3
GPU: sapphire r9 270x oc 2gb ddr5
HDD: 500 gb
Its in this boot-loop, it wont go POST, im going crazy because i invested in a "gamer" pc. I tried to take out a ramstick (2 different rams) and didnt work. I tried to take out the GPU, and try it with a diff GPU but it failed also. 
Im researching forever now, can anyone help me?
