Games freezing/crashing

  • I have a psp 2001 running 6.60 pro-c on a 64gb micro sd/mem stick and ive had it happen a couple of times now where a game freezes up and the only thing i can do is hold the power button until it turns off, can't hit the home but, no other inputs work and the screen stays frozen, sometimes the memory access light blinks rhythmically other times it doesn't light up at all, does anyone else have these issues and know how to fix it?  whatsapp web whatsapp plus
