Someone Help!

Hi, i recently built my first PC, my build list is as follows, i5 7500k, Gigabyte b250 motherboard, 8gb ram, 1050ti GPU, 450 watt psu, 1tb hard drive. Here's my problem, my computer runs fine on basic web browsing or video streaming, but whenever i try to play a game the computer freezes and goes to either a grey or black screen; and either restarts on its own or i have to press the restart button. When this happens the computer is unresponsive to ctrl alt del. Ive tested it with the unengine benchmark and it warrants the same results. i swapped the Gpu for a replacement and the problem persist, without the gpu installed i can run the unengine benchmark all the way through. So am i looking at a bad pci e slot??? any help will be greatly appreciated.

What drivers are you running on your 1050ti?

HAve you tried the newest driver after cleaning out the old driver installs?

What bios version is your mobo?

Try testing a different PSU?

i  tried a program that wiped the drivers and reinstalled them and it didn't change anything, i could have done it wrong but who knows. And the bios version is F2
