GeForce GT 520 died- I like to use EVGA GeForce GTX 750Ti over ATI Radeon HD 5670 in H8-1110

My GeForce GT 520 died- I purchased a EVGA GeForce GTX 750Ti (PCI3.0G) and would like to use this card over ATI Radeon HD 5670 (PCI 2.1G) in H8-1110 if possbile. My motherboard socket in this H8-1110 desktop pc is ATX LGA-1155. Will EVGA work with this PC? My friend and I tried the EVGA had no luck with it...even though PCI 3.0 should be backward comptiable, it is not recognizing once installed. I have EVGA 500 Watt PS already installed. I would like the EVGA to work first then Radeon without buying a new motherboard. Is this possible with my current one PCI x16? Help please!!! Thanks

Curious, are you trying to plug in an ATI Radeon and a GeForce GTX 750Ti together in the same system?
If that's the case, this is a big no, no.

No, one or the other...not both at the same time....besides my Motherboard only has one PCI slot
