Pc not working help please

[jamesvaughan711]

So my friend lent me his old gpu (radeon hd 4870) this is the first graphics card i have plugged into my pc. I put it in everthing is working and im trying to find drivers for it but my pc is picking it up properly. So i switch pci slots and plug everything back in and my pc does not boot. The psu makes a tiny noise so i know its on its non modular i dont think any cable is broken and i checked that everything is plugged in properly nothing smells like it has burnt and i have tried booting with everything unplugged and only one ram stick but still have no clue.

Specs

Asrock Z87 extreme 4
Mushkin 8gb 1888mhz
Intel i7 4790k
Corsair cx750w

Any help would be much aprreciated

The 4870 was a terrible card. Unnecessarily power hungry and ran ridiculously hot. The only thing worse than a 4870 is a 4870x2. There's a good chance your onchip GPU will be faster than that old dinosaur.

Does the PSU fan spin up? Have you tried resetting the BIOS, all hard drives unplugged etc?

Also, does it power up without any RAM?

Put the card back to the first slot...check your ram

Does it have power

obligatory: Did you try turning it off and on again?
