All fine and perfect until...

Screen & lines are no longer an issue on my iMac. I had it repaired years ago and the problem never came back.

But lately this same mac has been acting strange. As i pressed the space bar to trigger Quick View on a video on my desktop, the computer violently shut down. I couldn't solve it by my own as there was no key combinations during startup (as there was no startup at all, no noise, no fans moving, no light on the screen, no beeps... I tried unplugging it and holding the power button as well and i had to take it to an apple tech.

I was thinking of a dead power supply or maybe the motherboard. Two days later apple tech called back saying it had been the memory modules. The machine was perfect, he had tried it with his own memory units and it worked fine.

Yesterday, after 3 days of use with my old memory, the computer shut off again while using Safari, not much workload, I believe!



I'd like to thank my friend Javier for his tip: By removing the memory while unplugged, then plugging it and pressing the power button, unplugging it again and putting the memory back again, i am now typing this on it!

So, thank you Javier! Thank you very much!

Things i'd like to say:

1. I love time machine! I made use of it almost every day and when my mac started failing, i had everything backed up and accessible through other computers!

2. My mac might shut off again. I don't know the reason why, but by removing the memory and putting it back, it boots.

3. I tried to write this on Apple Support Forums and I couldn't log in with my username.

"An account utilizing this email address already exists. Only one account per email address is allowed on Apple Support Communities."


I never thought i'd need help on a mac. Everything just works, and it's plain simple, but this error message intrigues me; i do not know how to proceed since I'm already logged with my account, not registering with the same email twice.
