While installing my new GTX 960, my system starts to boot up. I see the "Gateway" BIOS screen then I get one short beep from my internal speaker it does this 3 times then the screen on my monitor goes to a blinking cursor in the top left hand corner. I am not able to go into BIOS or Boot Options or Safe Mode. Things I have tried thus far: Removed all Graphics drivers, reseated graphics card, reseated RAM, Flashed BIOS, I have also looked for a way to disable the "Secure Boot" my BIOS does not allow for the option and when I try SHIFT + Restart in Windows I see nothing in Advanced Options. Prior to this I was using a Radeon HD 6770 I had no problems with the installation of that card I was able to run Fallout 4 with it but after five years of use the fan blades started to fall off and it sounded like a helicopter taking off. Any help would be greatly appreciated.
