Need to post the exact Dell G5 SE model you have (Serial Number if possible). Since there seems to be several different models as both Kingfish and I have shown.
Found this Laptop Model Dell G5 SE 5505 Laptop model: Support for Dell G5 SE 5505 | Drivers & Downloads | Dell US
It has an Urgent BIOS Update from 05/22/2020, CHIPSET Driver update 05/21/2020, and AMD Graphics Driver update 05/21/2020.
Don't update any BIOS until you are sure you have the exact Laptop model to download the BIOS from. The above link seems to be your laptop but may not be the exact laptop model you now have.
It is best is to follow Kingfish advice and run the laptop's own updater to update all your drivers in laptop otherwise you will need to do it manually.
As Kingfish mentioned I also agree that you should open a Dell Support Ticket since it is such a brand new laptop.
Same problem here except I bought this - it only has Office and Minecraft installed. Minecraft bombs out sometimes reboots the computer completely. Its the only freaking game installed. I dont want to install other games because I dont want one software company pointing at another as the source of the problem. So far this is a 100% Dell and Microsoft machine and not installing anything else until this resolved.
Just received this two days ago so its a brand new install. Patched 100% - the only thing showing was an URGENT bios patch. Now it has that and we still crashing and burning. Was it a bad idea to go AMD? Or Dell? Cant imagine a game such as minecraft could potential tax the system to the point it bounces itself off the walls. I got this computer for my son so he would leave mine alone... now hes back on mine.
Hi everyone! I use to have the exact same problem with the base model ryzen 5 4600H. So I jump to the conclussion that the faulty thing was the GPU. I install all the drivers from dell page and nothing helped. I give up trying to fix it by myself so I contact dell(on the dell community page) and they respond fast. They get to the conclussion that the GPU was faulty and send a box to my house via mail(i didn't pay for anything) for a replacement of my GPU. Now I have no problems, you just need some patience because depend where you live, when they receive the system is a 10 work day fix.
Obviously they change all the motherboard. But the faulty thing was the GPU. The point is to contact with dell support for a replacement of the unit or repair it
