Q: Macbook Pro 13 crazy video and self rebooting after El Capitan

Hi!

I have a MacbookPro7,1 (Mid 2010) and after a clean install of El Capitan the computer presented some problems. It boots normally and, after some random time of use, the screen starts flickering or, some times, shows some color and the system restarts. When it restarts, no message with any errors appear.

I've noticed that the problem is more frequent when working only in the battery.

Can someone help me please?
