Hardware specs: MacBook Pro (13-inch, Mid 2012); 2.5 GHz Intel Core i5 processor; 4 GB 1600 MHz DDR3; Intel HD Graphics 4000 1024 MB Software specs: Mac OS-X yosemite 10.10.3; Some part of my screen blinks and looks like that laptop is hanged but actually its only screen problem. But i don't know whether it is hardware problem and software problem. I tried to close all the applications running to check whether it is caused by a software or 3rd party app. But that was not the case. I captured a video of this small error. Sometimes the screen gets a little messy. BUT EVERYTHING STARTS LIKE THIS VIDEO LINK IN THE DESCRIPTION https://drive.google.com/file/d/0B83BFdS489w1TUtMS0VZSDE1OWs/view?usp=sharing
Can anyone suggest what should i do?
