STM32F4 corrupt memory/damaged MCU

I've been working on a project on my STM32F4 Discovery for a few weeks now and it's been working fine. Today I connected a OV7670 camera and after uploading the code the discovery stopped working after a while for some reason. I removed all the wires that connect the camera but still it does not work.

I try to debug to see what is wrong but when I go into the SystemInit() function the debugger just hangs there and does not continue. The dissasembler just shows nothing after that. What is wrong? I tried a few times to erase the whole flash memory and reprogram but it did not help.

I'm using Coocox IDE and  STM32F407Discovery with stlink via usb
