Hello guys, So i built a new PC without a gpu then i purchased a new graphics card GTX 760 MSI twin frozr, The computer works fine without the new GPU and the motherboard post screen shows up and intel graphics 4600 works with the performance expected from it. However after i installed the new GPU the PC does not show the Motherboard post screen and it boots to windows directly. and when i installed the newest drivers from Nvidia the installation is normal, however games perform really poor, it even performed worse than my Intel hd 4600 on lowest settings, I tried going to nvidia control panel but it does not give me access. If anybody could tell me what's going on it would be much appreciated. Thank you very much.
