Still can’t understand completely what you mean it’s dying but yet you have video recordings? Also when I tried to play certain video files on the laptop videos can be jerky because of many issues such as not enough processing power, video card being weak, very low ram. Also SD card failure can be a big issue too, did you format it in the dashcam as suggested? Make sure to use a proper power supply otherwise you can be chasing issues non-stop. I just found out that on my truck the issues was a loose cigarette lighter socket connection that kept interrupting power, I kept blaming the product until I plugged in another device and realized it’s a socket. It appears that Street Guardian Support is trying to reach out to you directly also, have you spoken to them? Their support is one of the best in the business of dashcams.
