A few days ago and after disconnecting a hard drive from a costumer the screen computer from my macbook started to do black screen in some parts, very flashy and in triangle shapes, I don't know if that makes any sense, the things is after a few days the computer does not work anymore, it goes on but the screen appears like in the picture and after goes flat green and stops there. I have tried to re install OS from external reader which computer recognise but it stays loading without doing any process. Anybody has any idea what it could be? Virus on mac maybe?
Apologies for my English

Macs are not immune to malware, but no true viruses exist in the wild that can run on Mac OS X, and there never have been any since it was released over 12 years ago. The only malware in the wild that can affect Mac OS X is a handful of trojans, none of which produce the symptoms you described.

Read the What security steps should I take? section of the Mac Virus/Malware FAQ for tips on practicing safe computing.
 
Any possible solution?

Thanks very much for the information, do you have any idea of what it could be?
 
Could be a bad internal video connection - open up and check that the LVDS cable is properly connected.
Or, it's a bad LCD panel (the display itself), or failed logic board.
Hook up an external display to see if the display appears OK on the external. If it's good, then the internal display is faulty.
If you get the same bad image on the external, then you can assume that the logic board has failed.
