Is my gpu dead?

Things i already did. None of these things worked 1 - Tried DDU and reinstalling drivers 2 - Tried safe mode to install drivers 3 - Tried clean install on nvidia drivers installation 4 - deleted drivers from task manager and tried to install them again

What happens 1- My pc will crash while installing drivers 2- screen will glitch then crash or pc will be on but no signal to monitor. Unplugging my monitor cable and plugging it back dont give signal and i need to restart 3 - Drivers get installed , pc is still on and screen is gliched so i have to restart then when i try to boot my pc will crash at login screen Fresh Windows install , latest version.
