Gaming Notebooks

I recently bought this hp pavilion gaming laptop around October and there were many issues ever since I opened and have been using it. First of all, every time I open a game on the laptop, it runs for a few seconds then shuts down automatically. I then open up the laptop again and start the game again and it doesn’t shut down. However, if I close the game and if I want to open the game again, the same problem happens and my laptop shuts down. This was very frustrating. It is a new laptop and nothing happened to it but this problem is still occurring. Secondly, when I’m on the laptop, sometimes the Wi-Fi just randomly disconnects or crashes. It says (WiFi turned off. Turn on maunually) message. I tried many options to fix it and some worked, but the same WiFi problem keeps happening again and again making it impossible to use the laptop as I use WiFi all the time. Some weeks go by and I’m trying to use the laptop with the above two issues still occurring. I tried looking online and no solution. Then, I found a solution. The above two problems seem to be fixed if I run the laptop with no charger plugged in. However, this is bad as I game mainly so it is not good. I then tried to plug in the charger to the laptop and all of the sudden it shuts off. Now my laptop won’t turn on unless the charger is not plugged in. I heard this my be due to motherboard failure or something similar. This is a new laptop so there is warranty. Hopefully, there is some staff who are willing to fix this issue and get a replacement laptop that works properly without these problems. I have also heard some others had similar issues so I don’t think I am the first to experience this. I hope to get help soon.

EDIT: The laptop won’t turn on anymore. I tried to charge it by plugging it in but still it won’t turn on.
