My MacBook Pro screen freezes and shows black barcodes occasionally. Sometimes it happens with a scary roaring sound, causing me to push the power button immediately. It seems that without switching the power off, the laptop won’t restart itself. It happened the first time after replacing the original 2x2GB RAM with the new 2x4GB RAM and the original HDD with the SSD. See the picture above.
