Hi Adarsh, I am John J.D., a fellow Microsoft user like you.
I understand your frustration. I'm here to help. Has the issue started recently? If so, what changes have you made recently that might have triggered the issue?
Also, when you go to Device Manager and expand display adapters, are you getting any warnings? What troubleshooting steps have you already taken?
If you haven't already, please go to your computer manufacturer's support page for your specific computer model and download the most recent and recommended BIOS and graphics drivers.
If the issue persists, please provide more details about the problem. I'm here to help you with this.
John J.D.
