Decided to disassemble my fat ps3 to clean it out/repaste. Upon starting it up any time I try and open any program (retroarch, multiman/irisman, etc) it goes to a black screen and freezes. Everything worked fine before the disassembly. Any clue where to start looking for a problem? It's a chech A ps3 with a 300gig hdd and running rebug 4.82. Thanks for the help in advance.
