Microsoft Surface 7 Pro Shuts Down After 3-4 Seconds After Logo Help Finding BIOS

Microsoft Surface 7 1866 128 GB 021775602353 The computer was working when it came to me but it had a bios password. When I removed the bios chip, the chip was damaged. I bought a bios chip with the same code. I tried many bios from forums. They all shut down 2-3 seconds after the windows logo. I found a suitable bios. The touchscreen didn’t work on it and there was a problem with not seeing the ssd. I started looking for a different bios. Later, even though I wrote the bios that worked, it still doesn’t work. It shuts down 2-3 seconds after the windows logo. I think the bios chip is damaged.

And I have a question in my mind. Even when the bios eprom is removed from this computer, an image appears on the screen. How does this happen?
Is there anyone who can help me?
