Mid 2011 27 "crash and reboot the problem

just in the last week my iMac started having this problem. It occurs generally when the Safari. The screen turns blue, black or gray or sometimes deforms then hangs or automatically restarts. I did a scan of Apple hardware, and he says that he has no problem. Any help would be greatly appreciated. Here's the EtreCheck:
