Hi all,

I'm having a problem with my new graphics card. (Nvidia Geforce 750 ti EVGA Superclocked 2gb) When I install the new card and boot my PC I can't get to windows or BIOS, in fact I can't do anything, my keyboard doesn't work either. I just get a black screen with a blinking underscore. I sent the card back to Novatech and it's been tested and it's working fine on their end. However when I put my old graphics card in everything works fine again! (Nvidia GTS 520 - old card) It's just the new graphics card. I've even installed the latest drivers from Nvdia and my BIOS is up to date. Still no help.

PC Specs;
CPU - Intel i-5 2320 Sandy Bridge
Mother board - Gigabyte GA-H61M-S2PV rev 2.0
8GB RAM DDR3
PSU - Corsair CX600W
64 bit Windows 7

Any ideas here? Compatibility? As everything works well. One idea was an issue with the CPU not being compatible with the new graphics card. But would that be the reason it doesn't even let me boot?

Any suggestion here would be appreciated.

I had the same problem with an R9 290 and i just returned it and bought a gtx 960 and Windows booted up just fine. i would try to install the nvidia drivers with your old card in and then switch them out, that way you have the nvidia drivers booted and loaded when you plug that card in
