Mac taking more than 1 hour to reach login screen and other problems.

I have a 2011 Mac book pro. It is taking more than 1 hour to reach the login screen after I turn it on with appearance of silver screen for a long time.

After logging in or sometimes at the start up some horizontal or vertical black lines appear on the screen.

What could be the real problem for this? I have attached the images.

Please help.

Unfortunately the graphic card is saying goodbye cruel world.

It seems every day somebody reports the same experience on such Macbooks that have been subject to an Apple extended repair program ended almost a couple of years ago.

Avoid having it repaired unless you’re 100% sure che chip will be replaced with a new reliable one, reball’s and reflows are often offered by inexperienced or ruthless labs but they are basically a waste of time and money.

I turned on my mac 2 hours ago after many days.

The lines are currently not there.

But it took more than 1 hour to start.
