Please let me know what is wrong with my pc because I have no idea how it happened. I had just built my pc almost a month ago and few days later I turn the on and it continues to reboot after each unsuccessful boot. The whole screen is deep black and no sound is detected. The boot up last around 3 secs and then the pc will crash and boot up again everytime until I switch off the power supply.

Any idea on how I can check whether if its a problem with the ram or gpu?
