Hello, This morning when I started up my MacbookPro, there was some error with lots of weird computer writings. It said "shut down and restart", so I did. It then started up and stayed frozen on the log in screen. So, I pressed the power button. It restarted but now it gives me a frozen white screen (see picture attached) Does anyone have any idea what can I do to solve this? This laptop is only 3 weeks old!! Thanks a lot.
