Version 8.1 will not boot on Raspberry Pi 3 Version B

Good day! I have been running Version 8.0 on my Raspberry Pi 3 Model B v1.2. Today I went to do a fresh install with the latest version (8.1), and the Pi will not boot. I re-flashed my SD with version 8.0 and it booted. I reflashed with 8.1 again, and it did not boot (no output on the display whatsoever, no flickers from the green status lights on the Pi). Then I reflashed 8.0 and it booted again.

Any thoughts?
