Upgraded my RAM and now using SSD but have got black screen
After upgrading the RAM and going over to SSD, I’ve now got a black screen. I power up hear the ‘chimes’ and the fan starts but only three of the internal LED lights come on when I part attach the screen. I’ve connected the old hard drive and press ‘command’ and ‘r’ whilst holding the power button but nothing comes up on the screen. Any suggestions??
