Overheat + screen flickering

Hi all,

I’m in need of assistance trying to figure what is wrong with my MacBook Pro it’s been causing some unusual problems within the last month- nothing a smc reset didn’t fix. However, I️ left my MacBook unattended for all of 5-10 minutes, only to return to a white flickering screen and my fans blazing. The white screen will not go away no matter what I️ do. Any ideas? I’ve tried a PRAM AND SMC rest to no avail.
