How about posting a complete list of components including model numbers.

You seem to mention having tried two different motherboards with both behaving the same way. That would tend to indicate some other component common to both builds is at fault. Powersupply, CPU, graphics or ram. Maybe the case. Could be a misplaced standoff shorting something out.

I belive this is your board - http://www.msi.com/product/mb/970A-...

You should always benchtest before installing the hardware in the case. Coolmax is NOT a good power supply. Do you have the 8-pin CPU power plug connected? Does it even have one?

If this is the PSU you bought - http://www.newegg.com/Product/Produ... - it's a low end cheapie with horrible specs.

THAT and recheck that you connected the plugs from the front of the case correctly to the motherboard, the details are in the manual.

You have to be a little bit crazy to keep you from going insane.

well it wasnt the psu on the nvidia case i found the power hdd pins were marked wrong thanks to a review had it up and running but still have a problem turned it on today it does the same thing iam assuming it may be my sprankle 9400gt gpu, seems if i pull it out i get 1 long beep and 2 short beeps meaning the gpu i do believe, by the way you guys are awesome and i truly appreciate your help, i been building for a few but never run into this problem. as for the cpu i have an enhance 500 watt i swapped out i thought that was it but ill get a better one soon and use this one in a back up iam building.
