When I put in my graphics card for the first time, I had the drivers installed and my previous driver uninstalled (I think) However, when I started my PC, my computer is usually at 1920x1080, but now, I'm at 1024x768. Also, when I tried to play Overwatch instead of me having the usual 30 fps, I had 1 and it said my graphics card was the "Microsoft Basic Display Driver." So, I went to device manager and found that under display adapters was my graphics card, but with a yellow triangle with an exclamation mark next to it. When I clicked on it, it said I had error code 43. Then, I used a DDU and reinstalled it. This diddn't work so I tried about another 3-4 times. Still didn't work! Please help! Also, if it helps, I have a lenovo H50-50.
