what is wrong with my mac?
Basically over the past week my mac has suddenly started acting up, It seems perfectly find but then the screen will suddenly either turn blue(sometimes with white stripes across it), black, or just freeze up, sometimes the fan gets incredibly loud when this happens, sometimes its silent, when I try to restart it it wont get past the blue screen, on the occasion it does it will freeze again after a couple of minutes. The only way I can get it working again is to either go into safe mode, or go into disk utulities, or this : "Start your Mac while holding down the command and s keys. Continue to hold both keys down until you see a few lines of scrolling text on your display. It will look like an old-fashioned computer terminal. At the command prompt that appears once the text has stopped scrolling, enter the following: mount -uw / Press enter or return. Enter the following text: chown root / Press enter or return. Enter the following text: chmod 1775 / Press enter or return. Enter the following text: Exit Press enter or return. Your Mac will now boot from the startup drive"
Sometimes one will work and sometimes it wont, I just have to keep going through all the different processes until it works again, and when it does work again it will only work for a couple of hours, sometimes a day, and then it will happen again. When I do go into disk utulities it says that nothing needs repairing. Seeing as I've had it for 3 years the warrinty has expired and I can't afford to get it repaired.. :/
