Recently I bought a new graphics card, the GTX 770, as well as an EVGA 750 WATT power supply. After installing both of these in and powering on my PC, everything seemed to be working fine (fans were running, blue power button) but on my monitor it just froze on the HP "press ESC for startup" screen. I could not get any keys to work and when pressing certain buttons I heard beeping sounds.
I left in this new power supply and decided to try out my other graphics card, and when I powered on my PC everything worked like normal.
Could this be a defective card? Any comments are appreciated. :)
Now back to basics. With the AMD card installed physically to the mobo, go to programs and featured and uninstall the AMD Radeon HD 6570 drivers and shut down. Replace with the Nvidia card. Boot up. You should see the Microsoft default video out put?
If so install the drivers from the accompanying CD first.
I tried uninstalling the drivers from my old AMD graphics card, installing my 770, and it left me with the same problem as before. I couldn't press any key and it was frozen at the same HP logo screen.
As it's showing the HP logo you're getting an output from the Nvidia card but it's locking your system. Put the old card back and install the AMD drivers. The only way to check the card would be to try out on a different PC but not usually practical if you only have one. I'd contact the seller with your problem and explain the steps you have taken to trying to install the card. It could well be defective.
