My Lenovo Yoga 2 Pro is rebooting randomly. This started to happen today while the weather is hot and the temperature inside my living room is higher as usual.
I ran Intel Processor Diagnostic tool and each time it rebooted when doing the Roating Point test.
When I changed the power setting for maximum processor state from 100% (default) to 30% I ran the test again and it passed succesfully.

This is not a normal behaviour. What can I do to solve the issue? Do I need to replace the CPU or put new thermal paste or something like this?
