Turn the switch on on the power supply.

Then press the front switch. Don't think me harsh. I had a brain fart like that once.

I would suggest that you get a bigger PSU..

by Peconet Tietokoneet In reply to System Build

1) Your power supply unit is too small.
2) Start with just one stick of memory in the slot first to settle the BIOS (that is if you are putting in two lots of memory sticks).
3) Update the BIOS before anything else.
4) Check (and double check) ALL cables to make sure they are located to the correct pins and slots.
Post back if all works or not.

recheck what pins the power button connects to on the motherboard

by CG IT In reply to System Build

I've done that. Thought I had the cable on the right header pins and found out I put them on the wrong pins.

Check and Re-check

by TheChas In reply to System Build

I know I am not telling you anything that you do not know, but check and recheck all connections and mountings.

Check the setting of the clear CMOS jumper. Many systems will not POST when the jumper is set to clear.

Make sure that there is not a support post that is touching the motherboard.

I did not check the specs on the motherboard. Does it have on-board graphics?

If so, remove the video card and see if the system POSTS with just the on board graphics.

If the board has PCIe slots, it may not recognize a PCI video card.

I would also double check the voltage switch on the power supply. And, make sure you have all the correct axillary power connections made.

After checking all the obvious stuff, I start with the power supply. Either swap in a different supply, or plug a test plug onto this supply.

Then come choices on swapping out other components. Usually based on what I have on hand that is compatible.

Troubleshoooting Suggestions

by dmiles In reply to Check and Re-check

Thought I might solicit a reply from you,I checked and rechecked all the installation processes
This was was a high end brd
Assembled all the parts one at a time and when finished it would not even boot,no fans,hard drive,nothing reset the graphics brd,memory(no beeps when mem was taken out) and checked all connections,called Intel and the tech asked a few questions and finally gave me an RMA number
Now I am waiting on the board to get back,hopefully I have not gotten a board that I can't outwit,this is a first.
Thanks anyway and will post results when appropiate.

I'm with you. I like to be sure I have covered all of the basics before I call tech support.

While a bad motherboard is rare, they do still happen.
