Hi, so i had this problem yesterday and today pc shut down again.
Yesterday i was playing Mafia like 3hours and suddenly pc shut down.
Power led is still on, rgb od mobo is still on, cpu fan not working as well as rgb on fan. I cant turn on pc so i need to turn off PSU switch.
After that everything is normal but mouse isn't working so i need to replug it to work.
