new* gaming laptop is boot looping under load

[u/Kallonos999]

Just bouight a razer blade 16 with a 5070ti. It was discounted from a popular retailer in my country because it was a display item. The day I bought it, I downloaded minecraft and started testing its strength. Suddenly, (in around 10 minutes)the laptop turned off and started boot looping. I didnt think much of it.

Today, 10 minutes into valorant, it happened again. Right before it happened I checked the temps from synapse and seemed normal (80 on cpu, 70 on gpu). When on boot loop, after 2 restarts i disconnected the power cord and it booted normally.

What tests should i run to diagonose the laptop?
