Help don't know what's the problem

[Kyle1718]

I can't tell if my pci e slot or gpu is broken. Before I order 500w evga refurbished psu and evga 950 sc+ gpu refurbished for a budget build and I started it up and everything works for an hour. Then i ran a few games and it just turned off. My pc wouldn't turn off so I removed the gpu and now it works on integrated but I don't know if it's my gpu or pci e slot because I only have 1 pci e slot and no other place to test my gpu. I feel like I fucked the pci e slot because I sweat a lot pls help

You bought two used parts, one of those is likely the issue. Test those one at a time in a known good system.
