Ok so i dont have any RAM(i have gpu though) yet so this might be the problem too, but when i try to boot up my computer it doesnt run and the light next that says 'cpu' blinks red. This is when the top left cpu 8 pins has 4pins connected to the power supply. But when i remove these 4 pins it boots up without the RAM but nothing on screen(i know i need RAM). Why does it start up without those 4 pins and if i get RAM will it mess up my computer. Will try to give update in a few days when i buy RAM.

The power supply cable has two 4 pin connecters on it but only one of those actually can go into the motherboard eatx12V thing for cpu.
