Razer Blade 15" Advanced mid-2019 rtx 2070 not being detected in Device Manager & GeForce Experience

Hi all, My laptop was plugged in and on at night and I took a nap, during which the I think the rtx card stopped working because the external display I had connected was showing "no signal" and the icons on the desktop were all big and the background was black. Anyhoo, I did not realize the error until 2 days later when I reused the monitor. So far, I have reset Windows, uninstalled all nvidia drivers. I have been trying to reinstall the drivers from nvidia but I get the message that the drivers are not compatible with this version of windows and that no nvidia hardware was detected. I have been thinking of doing a manual windows reinstall too. Can anyone please tell me if they have ever experienced this issue before and what they did to solve it? Is it a hardware issue (as in the gpu is dead)? or more a software one? Also, is there a way I can use an external display with the laptop if the gpu is dead because I really dont want it replaced during school. I have contacted support but they are taking forever to respond and my warranty has been up for 11 days. I apologize if the post is messy, this being my first forum post. Please let me know if you need a System Information file. Edit: I forgot to include it above, but I have updated windows to the latest version and tried to install the latest drivers but the same error keeps on showing.
