Just purchased a Evga Geforce 760 graphics card based on some recomendations. The old power supply that i had was only 300 watts so i had to purchase a larger one for it. When i got everything all hooked up and ready to go the computer fired up and i was stuck on the hp loading screen(I have the hp h8-1160t) it will not let me enter boot menu and is completely frozen on that screen. Computer beeps once then there is a long pause and then it beeps again. After about 3 beeps the computer beeps once then 3 times very rapidly. I was thinking i could have possibly messed up my pci-e slot but when i put my old graphics card in(which is a geforce 530 model) the computer booted up just fine. What could be causing this problem? the motherboard i have is running AMI bios and i updated it very recently.
