Hello. I have a laptop that would purchased REFURBISHED and it has been great, except for one issue. Occasionally, when the computer is plugged in and using balanced or high performance power settings it will turn off randomly.

Trying to solve the issue, I have installed some monitoring programs, like CPU-Z, and the cpu cores run quite cool, staying around 40-50 degrees Celsius. But, I've noticed that my clock speed goes up to 3.4GHz on high performance and balanced power settings, even though my CPU is rated at 2.4GHz. So, I think that the problem may be caused by that.

I have no experience with changing the clock on a processor, but I went into my BIOS and saw nothing that could change the clock. I installed Intel's Extreme TUNING Utility, but many of the options are grayed out and I do not seem to be able to change them. I have attached an image so that you can see my options.

I don't really care about having it overclocked, I just want the processor to run with stability. Any help on what I can do would be very appreciated.

Not sure of what is rated or stated in TERM of CPU speed but check the Properties (right-click My Computer) to see if it's the correct output.It's a Lenovo Y50 with a Intel Core i7-4700HQ 2.4 GHz Processor.
