My computer was restarting randomly once per day, sometimes it didnt restart for few days..
Today when it restarted only blue light around power button was working. I tried to restart it again, turn off and on PSU and still it wont turn on. I noticed that PSU was very hot when it happend. Im assumig my PSU is dead but i need help to be sure.
