Please help me, i hope my mac is not broken. It's not booting up. Here's what hapenned. My mac was in sleep mode, i put it in it's bag and put the bag to the trunk of my car. It was also snowing and weather was 25 degrees fahrenheit. (-3 celcius) it was like that in my car for 2 hours and i came home, brought the bag upstairs, took it out of it's bag, it was amazingly cold. It didn't wake up. I plugged it in, turned it off with the button, turned it on and showed a huge green screen for a second than i hear the boot up sound, apple logo appears, loads the os and when it's time to select a user screen goes blank. I can turn on the volume etc all that is doable but can't see my screen. It's been almost an hour now and it's not cold anymore. Same thing happens. Can't boot it up. Also screen flikers when it's on the apple logo in the bootup. I've searched all over the net, tried running apple hardware test from the disc but screen shows nothing on that too. I've tried resetting vram, pram that didn't work. Called apple and they didn't help cause i havent got apple care. Please help me, any help is appriciated. My mac is 2010 15" macbook pro btw. Thanks in advance to all answers, i am writing this from my phone.
