Newly built computer won't startup first try, but will

[bubbaut]

I purchased one of those infamous Fry's ECS MB/CPU combinations to put in a MAME cocktail cabinet that I am building.

It is an AMD socket 754 2600 processor with an ECS Nforce 3A board ($69 total).

When I push the start button, I can see the CPU fan briefly spins, then stops. If I push it again, it does the same thing. After two or three more times, the computer will boot up just fine.

What exactly could be causing this issue? Is it most likely a motherboard issue, or a power supply issue? I am have another power supply (the one I am going to use in the MAME cabinet) on its way. I am hoping it's a power supply issue since Fry's is 70 miles away and my wife will kill me if we have to drive back to return it.

Thanks in advance!!

Hi, I would try resetting CMOS. If no luck......
Then disconnecting all drives.
See if the computer tries to start first time. - If it does, then it could be a suspect psu.
If not, check that the fan on the cpu is attached properly.
post back with the result.

Welcome to AT.

I'd say probably a PSU issue. What kind to you have?

I have a generic powmax atx 400w power supply. Clearing the CMOS just reset my time. Disconnecting everything coming off the psu except the mb and hd didn't help either...

might have to wait until newegg delivers the new psu. unfortunately, that will be an extra day or two now that ups is the standard instead of fedex...damn...

Try plugging the PSU connecter in hard. I once had an issue like that and it turned out to strictly be a PSU connector problem.

unplugged and re-plugged in psu connectors. still same problem.

any other ideas?

This reminds of me of the ECS Socket Mobo I had about 6 years ago. The darn thing, and in fact, the entire model of the particular mobo have the same problem, it won't boot the first time. But it will after two or three tries. Never did I bought an ECS mobo again. It's ECS achille's heel, onboard power regulator is just not good enough.

Well, got my new power supply from newegg and installed it (http://www.newegg.com/Product/Product.asp?Item=N82E16817181103).

It works like a champ.

Apparently my old power supply wasn't stable enough to provide enough power for the newer motherboard. Still works fine on my old motherboard. Go figure...

Thanks for everyones help.

This is the most common recommendation to correct the problem by using a more powerful PSU. But I went the other route by buying another mobo. I cannot see the logic in buying a $120.00 psu to make a $75.00 mobo to work when I can get a better mobo for less than $100.00. Anyways, if it's working for you congrats and enjoy.
