I had a similar problem before...
I think flashing relies on the internal oscillator of the stm32. So if you have flashed it succesfully and power seems not to be the issue, you may have problem with your external oscillator.
Make sure that it has propper connection and that there is no solder connecting the top of the housing to one of the pins. That fixed it in my case.
