There was a few models that Apple would swap motherboards but I can't tell what Apple model is under discussion.
Hi,
I encountered a problem yesterday where my laptop made a fuzzy noise and when blank while watching a video. I was forced to turn it off using the power buttton and when switching it on it beeps occured with a blank screen.
I tried to power it on again after 3 minutes and it worked. I again tried the video and the same issue occurred at a specific point of the video.
When I try to boot it up, it would hang on a white screen. But after trying again by selecting "mac HD' using the option key, I have no problems and it boots up. I try to copy some files and it hangs a little and then I had some horizontal coloured lines fill a blank screen
I did not use the mac until today. Now it boots up fine, the same video works, and I have encountered not problems with it all.
I am not sure whether I should be doing anything about it or not. I was suspecting a GPU or Ram issue. But I am not sure what I can do to figure out the problem and whether I should be worried about it. Please help
Thanks in advance
