Q: Diagnostic code- 4MEM/9/40000002: 0x794a2b90

So my computer has recently started to get really hot and I just noticed that sometimes the images burn on the screen So I decided to run the apple diagnostics test and when I finished it gave me this code 4MEM/9/40000002: 0x794a2b90 and it froze it took a total of 13 minutes running the test when it said approximately it would take a hour so just wondering what it could be sadly my computer is the mid 2012 retina display so I'm out of luck on apple support or repairs unless I pay. so if anybody knows I would appreciate it very much thank you

MacBook Pro (Retina, Mid 2012), OS X Yosemite (10.10.5)
