Hackintosh get's to apple logo, loads up to 50% and restarts

[CrashOE]

Hi this is my first time assembling a hackintosh and this problem is really frustrating

specs:
i7-3557 3.4GHz
Gigabyte Geforce GTX 960
Gigabyte GA-P75-D3

i followed the instructions of using unibeast to create the boot usb. I changed the BIOS settings also accordingly. But when I boot my hackintosh I get to the apple logo and it loads to 50% and then restarts my computer. I tried using -v -x but they dont seem to work, sometimes I also get the stop sign immediately without any loading bar showing up

Same with me.

this still happens to me a few times before it finally boots ... When I first built it though it would give me the same problem as you. It ended up being a bad stick of ram.
