So i upgraded RAM about 2 weeks ago from 4g ram to 8g ram. All was fine until this week. the problem is that, for me when i turn on the MBP it goes through fine. When i restart is when i get the 3 beeps but its not all the time.
When i google it, the results i get back are typically "bad ram or bad bank" so i began testing the slots (2 of em) and trying ever possible combination from trying one ram stick at a time , start, reboot, turn of, switch ram slot to other bank....rinse and repeat for the other stick etc...
All goes through fine. i gave up, put both sticks in, started, restarted and again, fine.
One thing i do notice is that...if im working on it all day, i close the lid and open it back up the next day, restart (to clear resources) THATS when i get the beep and it doesn't turn on. Thereafter, i have to open it up, re-seat the ram sticks and then itll be fine after that. BUT if i dont turn it off itll keep going with no problems.
Not a process i want to repeat every morning so any ideas as to whats going on? thanks in advance.
