Macbook pro shutting down even in very light usage.

Question

My macbook pro 13" early 2015 shuts down randomly. It shuts down even when watching youtube or any other very light tasks, then the next moment when I power it on, it won&#x27;t even reach upto the login screen. When I keep it idle just the screen turned on and doing nothing else it works for a very long time. I guess it is somehow related to CPU/GPU temp. Also when the CPU is is cold and I start it, the screen distorts and it takes nearly 5 mins to recover. Even after the screen recovers it is covered with equally spaced light grey very thin horizontal lines. I have already replaced the thermal compound and its was of no use. Is there anything else that I can do?

Watching video is not a light task. It uses a lot of both processor and GPU capacity. Some browsers can be quite tasking; Chrome is a well-known resource hog that can cause both Windows and Mac notebooks to run hot.When you had the computer open did you check the fan(s) for clogging. I recently serviced my MBP; I did not see much dirt on the fan blades but, on removing the fan, found this air blockage on the heat sink that the fan is supposed to cool:Your MBP model has a similar fan/heatsink config. It&#x27;s worth checking.Often hot running can be traced to either blocked air vents or unneeded third-party software. For venting, make sure that nothing like a blanket or pillow blocks the vents on either side of the case. Also avoid obstructing the hinge area in the back so exhaust air is not trapped in the computer.For the software issue there is an Apple procedure but it is dynamic rather than static. That makes it very difficult to post the results here without a lot of screenshots that may not be easy to for us helper types to read. Rather, you can post a snapshot of your config that can help us easily detect known trouble-making software. Fortunately there is a safe and secure way to do that.A respected and long-serving member of these communities has created a simple utility that will take a "snapshot" of your configuration without revealing any sensitive information about you and your computer. It is Etrecheck, and is available here:http://etrecheck.com/Run it and, when its report displays, click the "Share Report" icon and then "Copy Report" from the resulting dropdown. Paste the entire report into a response to your own thread here. It will allow us to quickly identify or eliminate software as the problem.
