Fragmented striped screen with startup and Apple Hardware test screen

Hi all,


Can anyway telling me what is going on with my Macbook Pro 2013 15" laptop? When I perform the hardware test it says "no trouble found". But clearly there is. It also starts up with a sort of green striped apple logo and then it blanks. I tried cleaning my RAM, reset the NVRAM/PRAM but no luck.


Tried to find people with the same problem, but so far no luck.


Anybody? Thanks for your time, much appreciated!

If you swapped memory, then you do not have a 2013 model, but more likely a mid-2012 model which is the last one with removable memory. It is a completely different system. It is possible the fan & heatsink fins have become clogged with dust or the heatsink thermal compound may be dried out and needs to replaced. "Heat treating" is not a fix and will more likely damage other components especially the plastics.
