Hi,

Built my first computer and when I turn it on the cpu fan and cooling fans start but only stay on a fraction of a second. I checked everything I could think of. Any suggestions???

Thanks.

Re-check the front panel connections, you may have the power button connection wrong. You may have wired the Reset switch to the Power Switch pins on the motherboard headers.

Checked that. However I am having trouble determining which side if the two wire connector is ground and which is power. The only indication on the connector is a small triangle on one side. Is that ground or power?


Tried it both ways and still does not work.

OK, lets eliminate the case buttons
Remove the case panel wires from mobo
Use a screwdriver to short the 2 power pins for a moment, does the PC fire up then/
If not, check for the motherboard shorting out on the case standoffs etc
Once your satisfied that it is OK try a know good PSU, if it fires up then, you know you need an new PSU

This could also be a short between the motherboard and the case. Make sure you're using at least 5 copper risers between the case and the mobo, and make sure that there is nothing (like a screw) caught underneat the motherboard.

edit - er...yeah...to expand on what Jack said. No reading comprehension for me today.
