Hello Tom's Hardware community!

My friend has an Intel Core i5-4590S that has been used for more than a year now. It has been running very well until yesterday.

It decided not to boot up my friend's PC, not even POST. So I tried the following diagnostic steps: swapping motherboards, removing the graphics card and using the integrated HDMI port, testing RAM slots... None of them worked.

I took a physical test by leaving the PC on for several minutes then I shut it down. Removed the heatsink and tried to touch the CPU with my bare finger. Neither the CPU nor the heatsink was hot.
I did notice that there was a lot of dust around the CPU heatsink area on the mobo.

What are the chances of the CPU died? And is dust the culprit?

Thank you for reading!
