Why Does My ESP32-WROVER-B Fail to Power On Intermittently?

hey, I'm experiencing intermittent power-on failures on my ESP32-WROVER-B dev board after connecting external peripherals, including a BME280 temperature and humidity sensor, MPU6050 accelerometer and gyroscope, 5V DC motor controlled via transistor, and 3.2" TFT LCD display. The board is powered via USB from my laptop and occasionally an external 5V/2A power supply. However, it sometimes fails to boot, with the power LED remaining off, and the issue occurs randomly, making reproduction challenging. Can anyone suggest possible causes and troubleshooting steps to ensure reliable operation?
