Specs:-Mobo;G1 Sniper 3 Rev.1 (F4)
-Cpu;i7-2600k
-Integrated Gpu; Intel HD Graphics 3000
-Gpu(trying get it to work); Msi gaming X 1060-6Gb
RAM;2x4 corsair vengeance ddr3
Power supply;Cougar 1200 W

My Problem is the PC only boots if I have my GPU out and using the integrated gpu from the Mobo . I tried flashing the bios and updating it .
I tried clearing the cmos several times .
I uninstalled all the Msi apps and drivers for the GPU.
I tried the dvi and VGA cable on the integrated GPU and it works ,but the Dvi doesn't work with the 1060,although it worked before just fine .
Every time I boot up using the 1060 I get stuck on the startup Gigabyte screen (boot options etc.) And get an error code b2 .
I also tried all other available pcie slots and same thing happens.
My monitor doesn't have Hdmi so I know for a fact it can't be a display problem cuz it worked before just fine (and I reinstalled the monitor drivers too)
I need help !!!
