Hello
I have a laptop lenovo Z510 and an i7-4702MQ CPU with an Intel HD Graphics 4600 and a nvidia 2Gb GT740.
after 4 years of using it and playing games, i had no problem. one day suddenly my laptop shutdown .... I had changed my windows, thermal paste, HDD, motherboard and ram but couldn't get rid of sudden shutdown. I even observed my CPU and GPU temperature exactly before shutting down but it was around 75 degree every time. the only part that i didn't change was CPU. is it possible that my CPU have a problem?
I used stress test on CPU, GPU and intel 4700 GPU but my laptop never shutdown. whenever i play games, and the charger is plugged in, after few minutes (5-30) it suddenly shutdown, without any warning or anything (just sudden blackness without power).
do you thing it's the CPU problem? did anybody see anything like this? I think my power supply is OK because i have also changed my charger.
