I know 'Graphic card beeping on startup' is a very common problem, but my problem is a little different. I have been using this graphic card for the past few months and it had been working fine. My graphic card is NVIDIA GT 630. My motherboard is Intel DH61WW. I installed the card on my own a few months ago. Yesterday, when I changed a few settings in 'Adjust the appearance and performance of windows' my pc restarted. And then I heard a beep from my pc. So in BIOS settings, I changed the default graphic card from 'Auto' to 'Internal Graphics', the pc booted up and then using device manager I changed it back to my graphic card. The problem is that whenever I try to start my computer with the 'Auto' option, I hear a beep! I always have to start with default graphics and then change back to graphic card. Can anyone help me?
