Hello. I am not a very experienced computer person. I bought a pc on kijiji with windows 10 that worked fine until I decided to upgrade the video card to a rx 480. I installed to computer and was stuck on a load screen for a very long time so I tipped the pc to the side to check some connections and my hand hit the power switch. Now when I boot up the computer the asus logo comes on and I can access the bios but the windows logo doesn't show up and the screen stays black and there is a blinking cursor on the right top corner. Did I brick my pc you think? Any ideas that could help me please ? thank you for your time.
