No boot, No beeps, Power LED on, Fans on - Take a Look!

I just got a motherboard replacement today; the first one did not power up. When everything is connected, this second one does power up - power led on, fans on, no boot, no beeps.

motherboard: http://www.newegg.com/Product/Product.aspx?Item=N82E16813128357

PSU: ULT-500P 115 or 230v
PSU is fine; works on a older computer (I checked it last time when the first motherboard didn't work)

Could it be that the PSU not providing enough watts?

When I got the motherboard the first time, I had to get a CPU also.
CPU: http://www.newegg.com/Product/Product.aspx?Item=N82E16819116072

But according to http://www.antec.outervision.com/PSUEngine , it should only need ~150Watts, more or less.

Via Google, some forums suggested to reset the CMOS. For the clr_cmos area, which I found out stands for "clear CMOS" (it has two pins) on the motherboard, there is no jumper on either pin. It came like that; I don't know if it's suppose to. You could also remove the battery, but I don't know how to - it seems trap in the slot.

For this: http://www.fonerbooks.com/cpu_ram.htm
I got down to "Runs on Bench" but I didn't know what that meant; also I don't know how comprehensive it is.

Ask any questions. My old motherboard was i think ~9 years old, and worked like a charm, but unfortunately one day it just didn't turn on ; I think it just needed a replacement of the CMOS (it typically loss the date/time when the surge protector was turned off), but that thought is too late now. I don't know what I should do.

 

If you only have 2 pins on the CMOS pins, pull one of the clips off an old motherboard or use one of the clips that you use on an old hard drive to select master/slave cs.

'Clip' thingy: OK, it is a jumper.:-D Look at the white plastic jumpers in the 5'th picture. http://www.harddriveupgrade.com/jumper_pins.shtml

Place the jumper on the CMOS pins with the computer unplugged, for a minute or so. Remove the jumper and plug it in and see if it boots.

That does seem to be a pretty small PSU for a modern computer. I would get a lot bigger one If I were you, but it might be ok. Does it have a plug for the extra motherboard power header? (White 4 pronged header in the top left of the mobo) And is that extra power header plugged in?

 

"extra power header plugged" - it doesn't have one of those.

no need for the jumper anymore since i got the cmos battery out (i hadn't done it before but was simple). how long should i wait for it to clear? what's i'm confuse about is that it should already have the factory default setting since it's a new motherboard.

 

With a minimum cpu, cpu fan, and 1 stick memory, I get the same result: No boot, No beeps, Power LED on, Fans on.

 

The mobo in your link shows an extra header for power. White 4 pin connector in the bottom left of the picture in this link: http://www.newegg.com/Product/ShowI...31M-ES2L Micro ATX Intel Motherboard - Retail

Is that plugged in?

 

"Is that plugged in?" - i said already that the power supply doesn't have that type of plug (I should've been clearer in one of the recent post), so the answer is no. that 4 pin connector is for ATX 12V; I'm using the 24 pin one.

 

So you don't have a power cable going to the extra mobo power header. I think it is time for a new PSU.

 

I don't think you need to use it. It's like having a SATA connector, and not using it because you have a IDE HD.

If i get a new PSU, and it still doesn't work...

This is from another forum in 2007: "..generally a motherboard that spins all fans and lights up but does nothing is a dead motherboard.."

 

Look at page 24 of your manual the 12v mainly powers the CPU. The 24 pin is for everything else. You need both as Fred said.

 

Are you sure your power supply doesn't have a 12v connector?

Is this it? http://cgi.ebay.com/Ultra-ULT-500P-500W-ATX-Power-Supply_W0QQitemZ150328994815QQcmdZViewItem

 

The PSU I currently have is black, which does not match the picture on Ebay, even though the sticker on this PSU has the exact name as the one used on Ebay. I can you with 100% certainty that there is no connector on the PSU I have that fits into the white 4 pin connector on the motherboard.

I wish the specs listed on newegg had provided the entire power requirement; all it says is "Power Pin | 24 Pin"

"You need both as Fred [suspected]" - Yep. Thank you SO much!! I'll find a new PSU, and post it back here.

Out of curiousity, did you find the manual online? Again, thank you for being a Major Geek.

 

Most Likely: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371007

Best brand they said for PSUs, and while it has 4 SATA connectors, it doesn't look like it has a IDE connector. What do you recommend?

The last post is suppose to say "I can [tell] you.."

 

Yep, I found the manual on the gigabyte site.

I think Fred_G did a lot more than suspect--he knows a lot more about hardware than I do. I'm just starting to pay attention enough to contemplate my first build.

I'm not sure if the ATX in the name signifies the need for the extra 4pin connector. It does seem like it should have been more clear in the specs.

Good Luck on finding your new PSU.

 

"I'm just starting to pay attention enough to contemplate my first build." - Joined in Nov 2006 with 1,616 posts, why do I find it hard to believe you, and that you're not making an implicit reference.

"more than suspect" - I mean that in a respectful way, and I'm sure it was based on his extensive experience.

"if the ATX in the name signifies.." - they have ATX motherboards using 20 pins or 24 pins only, so i'll guess probably not.

"new PSU" - I'll likely go for one with a IDE connector, since everything is on the IDE hard drive.

 

There are no specific IDE power connectors on a PSU.

 

The IDE power plugs are just 4 pin molex plugs. Used for some fans, CD/DVD drives...
I learned about the extra power headers on motherboards the hard way. :-D I had one board with 3, hooked up 2, it was unstable.:-o

 

"There are no specific IDE power connectors on a PSU; the IDE power plugs are just 4 pin molex plugs." - Ohh those.. for the power supply above, then how would anyone know how many molex plugs it has? Not even the official site, http://www.antec.com/Believe_it/product1.php?id=NjU= , has that information; they just want me to buy it..

 

I wasn't joking about just starting to pay attention to hardware specifications. I think I have gotten over my fear of installing a CPU after someone quipped "it is not rocket science". But PSUs can be proprietary and confusing.

On your link on the bottom left there is a link for connectors. http://www.antec.com/Believe_it/connectors.php?ProdID=27500

I don't see a picture of the main 20-24 pin connector. Maybe that is so obvious they don't show it, but here is why you want to take advice from someone other than me on hardware compatibility.

 

so that's how you got to that page... (I shouldn't have expected it to show along with the "4 SATA connectors")

"main 20-24 pin" - won't that be the "1 x 20+4 pin" (first picture)? 20+4 should be 24 - maybe they have the picture incorrect?

 

Yeah, it looks like they used the same picture twice.

But remember, you've had more practice connecting a PSU than I have. Last one I had that went bad was a Compaq and I took it to the shop because I couldn't find a suitable replacement off the shelf. Thanks to this thread, I'm learning what to look for.

The great thing about choosing well-known brands of MB, PSUs is they have lots of support documents on the web. Pic from the manual:

 

"main 20-24 pin" - won't that be the "1 x 20+4 pin" (first picture)? 20+4 should be 24 - maybe they have the picture incorrect?[/quote]

20-24 means it can be used as a 24 pin for headers that are 24 pin, or you can remove 4 pins and it will work on a 20 pin header.
