You can try the old reset and save your files. But as any PC you always backup what you can lose.

Lately, I'm having problem with my audio (none). And the video is slow and would keep buffering. I tried system restore to a previous date and it worked. Then the problem came again. I tried another system restore and it's no longer working. My laptop is HP and using windows 10. Anyone who can help?
