GTX1050TI can`t be recognize by Gigabyte GA-B150-HD3P?

[Jomgu1]

I have this PC:

Gigabyte GA-B150-HD3P,
Win7 X64 SP2,
16 GB DDR4 2133 Mhz,
i5-6500

i adquire a MSI Gaming GTX1050Ti 4 GB, and when i install drivers it shows in hardware manager gpu name but with a yellow triangle. I update BIOS, Chipset, and Drivers several times (trying all versions of nvidia drivers). And continue showing yellow triangle. I try in a different computer and recognize correctly (GA-Z170-HD3P, Win 7). I put in my PC hwinfo and shows in video memory: 16 MB when it must be 4096MB...

What can i try?

Is it getting enough power? Maybe an old nvidia driver still on your system? http://www.nvidia.com/object/IO_13955.html

Yes is getting 18A power Rail from this Power Supply: LC8850 (http://www.lc-power.com/en/product/archive/power-supply-units/lc8850-v22-arkangel/). I erase all nvidia drivers before with DDU. Before was installed a GTX950 and recognize at all
