She has a 2011 MBP, I'm fairly certain she did not upgrade to the latest OSX. When you turn it on, it turns on fine and then does the white screen with the Apple logo and the loading bar under the logo. It acts like it's loading up then when it gets to the far right, or the end.......it goes to a white screen.......sits there and shuts off. It's a backup computer for her, so it isn't imperative she gets it running again, but she would like to fix it. I'm assuming maybe something with the logic board? She said she even took off the bottom panel and sprayed it with a can of air to see if it just needed to be cleaned out and that did not work haha. Any input would be appreciated. If the cost to fix is more than like 250 she will probably just junk it.
