Q: iMac Graphic Issue - Crashes

I'm having this major issue with my iMac (Mid 2011). My computer "freezes" forcing me to restart it by long-pressing power button, then, after 10-15 minutes of running normally it crashes again showing a flashing/glitched screen


I took it to a Macstore, they test it and restore it, everything was fine and they were able to create a backup, until the return it to me, after 3-4 hours of normal use, it happened again. Im getting tired of this issue, any ideas on what should it be?


Sometimes if I'm playing a track in iTunes, the music goes on (2 seconds or less loops), but the screen just goes crazy .


I uploaded a video on youtube showing this error, hope it helps:
