Not sure if you remember the thread I posted a couple of months ago about my Macbook dying and needing to get sent back? Well, I'm having more problems now. When I turn my MB on, it starts up and as soon as the desktop loads, the computer dies. Then when I turn it back on it dies instantly. Turn it on again, it dies...and so on, and doesn't come on.
To get the computer to actually turn on, I need to hold down the power button for a few second and the power light flickers, then when I release the button the computer makes beeping noise, and turns on.
After that the computer works, it shuts down and turns on fine. Until it decides to do it again a couple of hours later, or the next day.
I'm sure somethings wrong with it, but I don't want to send it back again
Anyone else experiencing the same problem? Or, any problems?
Also, how do you lot clean your MB glossy screens? Mines gets dirty so easily, all I need to do is touch it and its got a big mark on it that wont come off.
