Recheck you power supply connections making sure the correct wires are attached and that they are completely seated in the correct places. Are you sure the ATX 12V EPS at the top of the CPU is connected and fully seated?
No...moved board in tact to new case....per above...one stick etc...same post error 1 long-2 short - ATX 12V EPS connected securely

Power leads appear to be correct but since I don't have the manual...can't be sure ?? Now I have board ID will double check power leads. Since this is a different case...all the lead id's are not exactly the same markings as the MB...will be checking that as soon as I get a schematic

Thanks all...!!!

When you put it in the case, are you sure all standoffs were lined up with the holes in the motherboard (6, I think) and there were no extras, and all were snugged down?

When you tried to start up last time, did you disconnect everything else? Only CPU and Ram installed, no Hard drive, DVD or anything else?

Yes....only six pins on case - six pin holes on board. yes...only cpu and 1 stick of ram installed

Attached is potential issue...are/could these two case pin connections be switched...do I have ground/hot reversed ? Will I do any damage to board etc...if I switch these 2 pins for PWRBTN per MB schematic attached ? The lead from the current case has this as 'Power SW' Should black / green wire be reversed ?

Any problems if I try these two reversed ? Have speaker connector removed for clarity.

Would the incorrect pin attachments on the power bar cause the failure to boot...ie 1 long- 2 short bios beeps ?

Thanks....TiminAz

I'll look, but the power button doesn't matter which 2, other ones it does matter.

I really can't tell from the picture, but again the power button does not matter. You can try disconnecting everything else.

When you do hook things up double check this connection. Sometimes it's difficult to get seated all the way. Also double check it the proper cable from the power supply.

Thanks LB....the old board in this box did boot ok after a number of tries previously....so the power cable seems to be ok....I think there is/are 2 4 pin cables for the jack you indicated so I'll check both if there's still an issue....
