No power-up on newly built computer.

Just finished putting together my 4th computer, all hardware is new.  Problem is unit will not power-up.  I think the case connectors (Power LED, HDD LED, PWR SW, RESET SW) are some how on the wrong pins on the motherboard.  MB is a PCChips 841LR, micro atx, with a 1.3G Duron, heatsink-fan, etc.  The book that came with the MB isn't very explicit, I know that all the connectors are attached to SW1, but the POWER LED coonector is a 3 prong and by the time everything else is where I think it should be according to the schematic, there isn't room left for the connector.  I hav scoured the book and the motherboard to see if I have missed something, I've checked all the connections from the PS, but don't find any problems.  Yes, I've checked the outlet and the Power cord as well.

Is there any other "hidden" problems I should be aware of?  Anyone with any knowledge of this MB - I wouls appreciate the help.

The Power LED switch shouldn't keep your system from booting.  Your Power SW is the one that matters at this point, and the only one that truly matters.  I have looked at the manual for your board.  Be sure the Power SW is located on pins 2 & 4.  Also, if you just got done building your computer (this is kind of a redundant question) but did you turn on the switch to your power supply?????  All of them come default on the OFF position.

most of the ATX power wire/connectors I have seen are 2 wire. I would pull all the discrete wires to start with, you only need the power one, and just hook up the wires for the power switch

looking at the manual, it goes on pin 2 & 4 of your SW1 header......... are you sure you aren't trying to connect a POWER ON LED connector to it... they are usually 3 pin sockets with only two wires in them.

follow the wires from the back of the power on switch these are the ones you will need

I tried everything.  I only hooked up the PWR SW to pins 2&4 of SW1.....nada.  I tried reversing polarity....nada.  I took off the front plastic cover from the case and traced the wires back from the PWR SW to make sure that I had the correct connector....nada.  I checked to make sure that the power supply switch was turned on as well.....nada.  However I have a case fan which is not hooked into the MB, but hooked directly to one of the power supply cables.......shouldn't this fan run no matter what when the power supply switch is on?

Hey Greyguy.....I think it must be the MB.  I removed the new MB and put the old MB in the new case and it fired right up.  I think I've eliminated everything else, it has to be the MB.  I will order a new MB, but not a PCChips, I'm going to order a Biostar instead.  I guess I'm soured on PCChips.

Biostar are good boards, but also look into ASUS.. they have great performance!

Hmm, just guessing here, it's not because you installed the fan to external power is it? Maybe the mobo has some check to see if a fan is connected??

NicoLaan....No, I checked and rechecked the fan connection.  The manual is specific as to where it should go and I put it where indicated.  I checked and rechecked all connections and seating of connectors numerous times.  I read the (short) manual that came with the MB over and over thinking I may have missed something like a jumper or something, but found nothing amiss.  I hope to have better luck with the Biostar.

I'm building this for someone else, but I noticed that my own personal MB (Abit KT7 Raid)came with quite an extensive manual which was very detailed.  Not so the manual that came with the PCChips MB.  I'm not familiar with this brand, but I must say I'm not impressed.

Thank you all for your attempts to help out.  I really appreciate it.  You guys have really helped my many times in the past.  This time.....it seems to be faulty hardware.

PCChips/ECS-Elitegroup are some of the worst motherboards you can buy.  yes, they're cheap and its for a good reason; you get what you pay for.  I don't know how many people we've helped who bought an ECS K7S5A and were having all sorts of problems with it.  They are true garbage and I'd never buy anything from them.

Glad you got your problem resolved!
