Laptop shutdown automatically

[rob.robber20]

I have lenovo z510 i7 4702mq cpu and gt 740m gpu whenever i play games or use it under load after sometime its shut down automatically the temperature is about 72 celsius i am using win10 (home) i use my laptop plugged in

Could it be running too hot for too long?
If the screen goes black without it actually turning off it would be a graphics card driver crash which is caused by running something the graphics card can't handle for too long.

There is no black screen it just turn off completely without any warning. Its only happans when i use it under load normally works fine. When i play games sometimes it takes about 10 minutes to shut down or about 30 minutes i have also replaced my adapter but same problem

To isolate the issue, you'll need to stress both the CPU and GPU independently.

For the CPU, run the Intel CPU diagnostic or Prime95 for 20 minutes or until the laptop turns off.

For the GPU, run FurMark

I see three possibilities. GPU, CPU, or the motherboard itself (bad VRM, etc). In any case, you'll probably have to contact Lenovo for an RMA assuming it's still under warranty.

Do i need to replaced my cpu

 

[stdragon]

Replace the CPU? Possibly. It's also possible that the tests failed because of a problem with a SODIMM (RAM module).

You can try downloading and running Memtest86 and the official Lenovo utilities. If it's under warranty, they should be able to assist with the RMA process to get it repaired.
