PC will not start

I built a new pc and can not get it to start up when I press the power button. thecase fans and cpu fan spin for half a sec then stop. Iâ€™ve tried switching the psu with one I know works and still nothing they both light up a LED next to the 2 * 12 plug on my Intel BOXD975XBX2KR.

So I think the problems the CPU or the motherboard, could a defective CPU stop the system fans spinning and with a bad cpu would the system beep.

also if i only have my psu connected to the Motherboard no cpu, ram and just a case fan want would happen e.g. would it beep or just not start

try unplgging all drives, power and data cables, reboot, if it posts plug one at a time in until it fails, good luck.

Try goint through the checklist in the manual for the board. It has a full step-by-step guide to finding what the problem is.

EDIT: Just looked through my manual - it's not there, my mistake. Its actually a poster-type paper that comes in the box, if you bought it retail.

Did you only use 10 mounting post and screws ?
Are you using the stock heatsink/fan ?

If worst comes to worst try taking the motherboard out of the case and
wiring up the powersupply to it - maybe you have a short somewhere.

yea im using the stock heat fan for the cpu and i've got the mb out on my desk so there are no screws in it. i've got it down to a cpu and mb it should beep 3 times but it just dies in half a sec.

Intel says 3 longs beeps, 1280 Hz, means memory error.
http://www.intel.com/support/motherboar ... 025434.htm

With motherboard out of the case.
Install one stick or all of your memory.
Install graphics card .
Wire up you monitor to graphics card.

If all goes well then atach hard drive and Opical drive.

good luck
