I have a bit of an issue with my MacBook Pro late 2011 13". While I was working it slowed down, so I decided to shut down all applications and restart the computer. In the booting process of rebooting the screen started to flicker and eventually it turned black. I restarted again and after the starting peep tone the screen turned to black and white stripes. I googled for that issue and soon had to find out that probably the graphics card is overheated/dead.
However, I just started the computer again and everything worked well and I was even able to login again. After a couple of seconds it started to flicker again and then the stripes appeared again.
Now I'm not sure whether the graphics card is dead or not, as everything worked perfectly fine for a moment after the issue appeared for the first time.
Any ideas what I could do or what causes the issue? ...I'm currently working remotely from Indonesia so I can't really get any help from an apple store.
Thanks in advance, any help appreciated!
