Won't boot up, just turns off!?

[jackson10t]

So my computer has been working perfectly for the last 6 months or so, however for some strange reason when I boot up my computer it just turns off after the apple screen. I tried unplugging the power and resetting it, no luck. Any suggestions?

Make sure your CPU fan is working. Most motherboards will display this behavior if the CPU fan is dead, to avoid killing the CPU.
