I have a STM32F407VG6 DIY board

The board can't function properly, it can be downloaded using ST-LINK but the output doesn't match with the program I wrote. Is it because the oscillator? I watch the oscillator signal and it is different from the right board. The other DIY board has more problems besides the oscillator signal, the VCC pin voltage is 0 V and the reset pin voltage is 0 V. Can anyone help troubleshooting these problems? Thank you.

Start with a schematic of what you've actually created.
