Why does my Mac sometimes doesn't want to startup?
I've changed my Mac's storage to a SSD (Corsair Elite Force 480 GB) which was working. Then, one day my Mac won't startup, I figured it was the SATA cable was not working. I bought a new one and exchanged it. Now it sometimes it so laggy I shut it down from the power button and sometimes it starts up with a blinking question marked folder!!
Please help! =D
