CPU Fan spins for 1 sec then goes off

fetster · 15 Jun 2011 at 09:27

I have just assembled a machine and turned it on. The CPU fan spins for 1 sec and then stops, no display on the monitor and no lights on keyboard and no POST beeps.

Any idea what could be wrong?

Did you plug the 4 or 8 pin CPU power connector into the motherboard?

Check all cables are in properally and take out any add-on cards you have in (Graphics, sound cards) and then see what happens.

Could you list your full specs.
Double check memory are in the correct slots and also try a CMOS reset.

You didn't mention what type of PSU you have. Can you try jump starting the PSU to see if it stays running? There's a guide here.

Is it a Core2Duo or Pentuim 4, Celeron?

Have you checked the power and reset switches are conntected properly? You can also try removing all the front panel stuff and starting it by touching the two pins with a screwdriver instead.
