Screen flickering and after reboot mac stuck on booting screen
Hey guys,
I kindly ask for your urgent support on a screen/monitor issue on my macbook pro 15".
I have a macbook pro (A1260, osx 10.6.8 snow leopard) that ran smoothly until 5 mins ago when I was browsing the internet and the screen start flickering (blinking "stripes" appeared on top of the webpage I was on). It became unresponsive so I had to shut it down by removing battery.
Now when I try to start my mac, it starts up but stays forever on the booting screen (the white screen with apple logo and the loading symbol): when it's supposed to switch to the light blue blank screen just before showing my desktop with all the icons, it just remains on the white booting screen and the loading symbol stops loading/freezes.
If it weren't for the screen that stays frozen on that white booting page, i'd say the booting process is succesfull because, even screen still shows white loading page, if I press volume keys I hear the volume sound going up/down and if I press thepower button and then either press enter key or R key on the keyboard, the computer shuts down regularly or reboots depending on which key I've pressed, just as if shut down menu had appeard regularly on the screen...
I have already tried to reset pram and smc, but so far it did not work.
Could any please give me some directions on how to fix this?
Thank you so much
