So I have a laptop that's several months old, it's using an intel i7 9250H with an RTX 2060. Recently when playing certain games the games would immediately crash to desktop. After this when turning the computer on the fans would spin up to max RPM. Assuming that overheating was causing this I disassembled the laptop and cleared out the fans and the vents in the heat sink of dust. Computer ran fine for a days but I began getting the same problem again as well as a BSOD with the error video dxgkrnl fatal error. Assuming something was wrong with the fans again I checked them again and they were operating fine.

I checked the temperature on the CPU and GPU and noticed that when the computer starts up the CPU can reach into the 80s and even 90s (Celsius). I stress tested both the CPU and GPU however and found nothing wrong the GPU maxed out around 70c while the CPU would hit 94c on one core and 70-80c on the others however both GPU and CPU would go down to 30-40c right after finishing the stress test and the fans seemed to be working just fine in cooling the system. There was also no errors or any indication that the computer couldn't handle the stress test and was failing so I assumed hardware wasn't the issue. Assuming the driver might be an issue I rolled back the GPU driver but this hasn't solved the problem either. Also after rolling back the GPU driver the sensor indicates that the GPU is at 0c but will show the actual temp when the GPU is in use.

At the moment I'm at a loss for ideas, the laptop is still under warranty and they've offered to look into it if I send it to them, problem is that covid has locked all the state borders in my country and I most likely won't get the computer back for months. I don't want to send it in for warranty replacement of parts if it's a software issue I can fix myself, I don't know how what else to do on the hardware side of things as sometimes the GPU fails just randomly playing mediocre games yet can handle multiple stress tests from multiple different programs.

tl;dr Computer is getting me a video error. I've cleaned the fans, rolled back drivers, stress tested all the components and they handle the stress testing fine. Something is wrong with the temperatures but no idea what it is. Help?
