Problem UEFI and White Screen

[nachorevuelta99]

Hi!

I've a computer with the following specs:

Motherboard: Gygabite Z87P-D3
CPU: Intel Core i5-4670 @ 3.40GHz
Graphics:Nvidia GTX 650ti 2 GB
RAM: 8 GB

And, it's supposed to be UEFI (In fact, I had a Hackintosh in there a while ago). When I set it up with Unibeast, (in UEFI mode), my computer doesn't detect it as UEFI, (and when i click on load from USB) it loads Windows. And when I set it up to Legacy Mode it boots but after apple logo appears and keeps charging the screen goes black... I don't know what to do

I forgot to tell that I've reset the Bios via CMOD (Or something like that) and loading optimized defaults
