Startup often restarts with granulated screen, eventually boots

crwdns2934249:0crwdne2934249:0:

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
