Pc has died-wont turn on

[Andy Pandy]

I am typing this from my phone so I apologize about any typos . My computer has decided to die, when ever I push the power button all the fans come on as normal but it dies a second later. It Will keep trying to turn on but it won't. Any one got any ideas on what's wrong. Thanks

Try resetting the CMOS and test with only one memory module installed.
