Today when i tried to update the latest Nvidia Experience version on my laptop, and after finish downloading, it required me to reboot. After rebooting, my laptop appear the Nvidia Experience HUD and installed the new version for a while, then I looked up for new graphic driver update and I found one, i tried to download and successfully installed the lastest one, it also required me to reboot. After rebooting, my computer didn't detect my graphic card, there is no nvidia panel and i also check in device manager and there was no.
I have tried to uninstalling the graphic driver and set BIOS to default, at first my laptop finally detected my graphic card, but when i reinstall the graphic driver, it required me to reboot. After rebooting my laptop cannot detect my graphic card again :( what can i do now?
My graphic card is gt820m
