The screen (Apple logo and slider bar) upon startup are often ‘grainy/pixelated’ and more often than not system will reboot on it’s own. Eventually it will boot and all runs well, screen, wifi, bluetooth, internal keyboard/touchpad, etc.. Left fan I know needs replacing as most times it’s not running. My concern it the startup attempts/behaviour. Am I looking at a logic board issue (video chipset on the way out)? Any thoughts please
Sadly finding parts for this series group is quite hard! I would leave things alone and save my pennies for a newer system. In addition I really don’t recommend connecting to the internet with this system as the OS9 and OS-X this series uses is not very safe! Assume anything on your system is exposed to anyone (Spyware) and you may risk loosing your stuff from Malware & Virus’s!
