RPCS3 constantly crashing

Hello, my problem is the following : when I tried to do launch a game RPCS3 crashed, so I tried reinstalling a newer version, but now I can't even install a PS3 firmware. On top of that, when it crashes I have to completely reboot my computer, I have no error message, nothing.
Everything worked fine two months ago though.
My config is : 
CPU: Intel Core I5 3450
GPU: Geforce Gtx 1050-TI
Ram: 8GB

Thanks in advance for your help !
