How Can I Tell If My Motherboard Is Bad?

[DALATINASSASIN]

I JUST BUILT A BRANDNEW PC. PUT IT ALL TOGETHER AND NOW IT WONT POST. I TRIED IT ALL FROM MEMORY TO RESETTING ALL THE HARDWARE. I EVEN SENT BACK THE PROCESSOR AND GOT A NEW ONE IN RETURN. SO HOW CAN I GO ABOUT CHECKING THE MOTHERBOARD? I WANT TO KNOW IF THE MOTHERBOARD SHORTED OUT. ALL HELP IS APPRECIATED.

MOTHERBOARD-INTEL-D925XECV2
PROCESSOR-INTEL LGA775 3.4 DUAL CORE
HERE'S MY POWERSUPPLY

For a new build, remember to clear the CMOS 1st before powering up the system for the 1st time.

With only 22A on the +12V rail, this 680W PSU is not a good one for a 3.4GHz dual core processor. Try to get a PSU with at least 30A-35A on the +12V rail. All cheap power supplies always have large amperage on the +5V and +3.3V to inflate the total wattage for marketing purposes.

Thanks for all that info. So you think the Pc is not posting because of the Powersupply? If it's not to much of a bother can you suggest a Powersupply to buy? Something affordable.

Thanks for all your help.

With the lack of juice, the system can't boot. Today's dual core CPU's require much more amperage than the older CPU's. If the +12V rail doesn't have enough current, even if we could successfully boot up the system and load Windows, we would experience many problems later.

How much is "affordable" we're talking about? :)

[DALATINASSASIN]

Would Say $60

Check the PSU's on this page (http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=2010320058+50002177+1131414178&name=Rosewill). They're very decent ones for your budget. Please remember to check the specs to make sure the one you want to purchase has a min of 30-35A on +12V. If it has more than one +12V rail, the total amperage on all +12V rails (V1, V2, ...) must also be at least 30-35A (the higher the better).

Thanks man.

[Van Nugent]

OK, bud.

[DALATINASSASIN]

Hey me again. Will this work?

[Van Nugent]

Yep, it should work fine.

[DALATINASSASIN]

Dude is it that important to have a PCI express cord with the powersupply? The one I showed you does not.

[Van Nugent]

Some video cards require extra power via this connector. No if your video card doesn't require extra power and yes if it does. You can also buy a cable with this connector separately if your PSU doesn't have it. Obviously, a PSU that supports SLI would come with at least 1 PCIe connector (always 2, I believe :)).

[DALATINASSASIN]

I'm buying this one. Is this o.k?

I didn't include it in the list of recommended PSU's because I believed it had reliability issue (probably one of the components the manufacturer used to build this PSU was not well designed/made). Just stay away from it at least for now. :)

How about these:

Pick one out of these 3.

[Van Nugent]

Go with the 3rd one if you need a PCIe connector or if you want to beautify your windowed case. Otherwise, I would choose the Coolmax. Actually, all 3 are great.
