I know enough about computers to really mess one up! LOL What I had a problem with was playing online movies and videos. I could watch anything on YouTube. If I tried any other such as Amazon Prime Video or Tubi the screen would go black, flash on, then go black.I ran the Windows Trouble Shooter. It said that I needed HEVC CODEC. So I found what I needed on Microsoft Store for free. Still didn't work right. I contacted AMD, they are who makes the video card in this computer. They had me download a driver. FIXED! Sorta..... The default video player is Windows Media Player. I had to download VLC media player. Now it works.This is a lot of work and studying for a person to do in order to get a product to work as advertised. Like I said, I know just enough about computers to hunt down a solution. By the time I had it working I had spent 7-8 hours reading and searching.Somebody that knows about computers might have been able to fix it in moments.Would you buy a rebuilt car if you had to reinstall the new parts correctly before you could drive it?
