Computer doesnt power on randomly

  1. Hello everyone.
    Ive read this forum but im not seeing the same situation that im dealing with so here it is. When I turn the power on, the light on the motherboard comes on the fan spins briefly but that's all that happens. The drive lights don't come on, the cd drive doesn't open, no drive checks or beeps are done. I tried all the basic power source checks listed in other posts. What is different is that sometimes the computer will complete booting up and run great. Other times I will turn it on and nothing but then within 3 to 5 minutes it will just turn on and run fine. Im trying to figure out what could be working great sometimes but then not work at all or randomly. My guess is the PSU or MB. Thanks for your thoughts

    The power supply is cheaper than a motherboard, so swap it first
