Hello Gordon Osmundson, welcome to Microsoft Q&A forum.
To help troubleshoot the black screen issue on YouTube, I need a bit more information:
- Which browser are you using? Does this happen on all browsers or just one?
- Does this happen only on YouTube, or also on other video sites?
- Can you play local video files in apps like VLC or Movies & TV without issues?
- What type of GPU does your PC have?
- Did you recently install any Windows updates?
These details will help narrow down whether it's a browser setting, graphics driver, or system update issue.
In the meantime, you can try:
- Use Youtube in another browser
- Disable hardware/graphic acceleration in your browser settings
