PC froze now won't boot

  1. Hi, I have a gaming PC that I built about two years ago. I was playing Minecraft (CPU and memory intensive) and the computer froze and wouldn't respond to anything including ctrl + alt + del. Its never done this before so I held down the power button to turn it off but now it won't turn on again. When I press the power button nothing happens, but when I turn the power supply switch off and on and press the power button, the fans will spin and lights will come on for half a second then turn off. I thought maybe the CPU had overheated but after waiting a while it still didn't turn on. I also tried clearing the CMOS and cutting the power, neither changed anything. The motherboard standby light is on.

    I searched around and I think it might be a bad power supply, any ideas? Thanks

    The power supply might have failed...
