logic board failure

Back in June 2012 when I gazed upon the newly released MacBook Pro with Retina display, I know that it was the machine I wanted to purchase. It ticked all the boxes; had good battery life, great screen, CPU, GPU and all I wanted back then. Sadly the demand was rather strong and I waited for 2...

My father has an iMac (Late 2014 27 inch Retina 5K) where he was experiencing screen flickering. He brought it in to his local Apple Store (in Florida), where they initially said it was the power supply, which they waived the $67 part cost to replace. But after replacing, they said the issue...

Everything went well putting back together. Start it up and hear the chime... then black screen with 2 LED's showing on the...

Why do logic boards fail when installing El Capitan? I seem to have had an instant failure on my 2012 27" iMac. Any ideas? Machine is not used frequently and am quite disappointed. Plus the fact my 17" MacBook Pro just had a logic board failure. Getting tired of this.
