Question Pc won't turn on and I suspect it's the CPU

Jan 23, 2021

My computer was working perfectly and after flying it to the UK simply stopped working completely, not a single light from motherboard or fans rotating (only rotating if connected directly to power supply and not through MOBO, but MOBO was tested by professionals and its working perfectly).
I suspected many things, this is all I tried:

  • Bought a new cable for power supplier, since I moved to a different country and plugs are different;
  • Tried on different wall sockets;
  • Check cables ( remove and plug cables again );
  • Start the computer by jumping the Motherboard, removing the chance of power cable not working, also tried starting with reset button;
  • Test Power Supplier, replace for a different one;
  • Sent Motherboard back to supplier, they made tests, working correctly;
  • One RAM at the time;
I think it's probably the CPU causing a short or something (maybe SSD ? or fans? cooler?), I had it removed and no burned signs or anything, all pins okay!
First time I'm using AMD products.


Processor AMD Ryzen 5 3600X Hexa-Core 3.8GHz w/boost 4.4GHz 36MB SktAM4
Motherboard ATX MSI B450 Tomahawk Max
RAM G.SKILL Ripjaws V 16GB(2x8GB) DDR4-3200MHz CL16 Gunmetal
Case ATX Sharkoon LIT 200 RGB
SSD M.2 2280 Kingston KC2000 500GB 3D TLC NVMe
Graphics Card MSI GeForce RTX 2060 SUPER VENTUS GP OC
Power Supply Seasonic S12III Series 650W 80PLUS Bronze

I appreciate ANY HELP!
