I recently bought an Nvidia GeForce GTX 770, but when I try to boot the PC, I get to the blue HP screen with the option to "press esc for startup menu", but no further. After a short while, there's a beep, followed by another beep every 30 seconds until the 4th beep which is quickly followed by three short and fast beeps before the monitor loses signal from the PC. If I press esc, I get to the black screen that shows the PC specs, but I can't press esc again to get to the startup menu, and eventually the beeping starts and the same as above happens.
What could be the problem here?
