iMac with weird lines and keep crashing
Hey guys what’s up! I just bought yesterday a 2009 iMac 2,93 GHz 4GB of RAM.
Previous owner said that there was probably an issue with graphic card due to small lines on the screen. So I opened it up, added a new HDD because it was removed and cleaned all the dust that was making the System running like an aircraft with fan at 100% Now it’s silent as my phone. After all that, i just reassembled everything and did a fresh install of Mac OS-X El Capitan. But after that, the computer is now crashing and freezing when I move the mouse. CPU is at 20 % something like that but it makes weird lines and sometimes fan are running super fast without reason. Here are some photos. Thanks for help
