I recently bought all new parts to do a completely new build. However when everything was all put together the motherboard would not post at all. I'm currently at work so I can't get into specifics but I can give a general run down and hopefully get a few ideas that can be tried before I have to settle and RMA it back. Bare in mind that everything is brand new and has never been used in an old build before.

My build as follows:
Asus Crosshair V Motherboard / Thunderbolt Edition
AMD FX-8150 with Corsair H80 as CPU Cooler
G.Skill Sniper 1866mhz 2x 4gb
Sapphire Radeon 6950 2gb Dirt 3 Edition.
Corsair TX750 watt PSU
CoolerMaster Storm Enforcer Case

Everything above was installed and attempted to boot however there was nothing. Hitting the power button caused everything to come on, the fans, some LED lights (which ones I can't recall at the moment) and such then about 5 seconds later everything would just power off again. Then everything was taken out so it was just the Motherboard, CPU + H80 and
RAM. Tried again, there was nothing. Then the ram was removed so it was just the motherboard and cpu. Still nothing, no error beep codes or anything. (Which makes me think the board could be dead)

Few key things that are different/unusual. The H80 only has a 3pin connector as opposed to the typical 4pin connector that a cpu fan has. Also the motherboard has the typical 24pin power and the 8pin power connectors however it also has another 4pin power connector that I DID NOT hook up as the TX750 does not have another 4pin to spare. I did some searches and came to the conclusion that the motherboard should NOT need this power in order to boot and was only required for extreme setups / overclocking. With the recent reports that the FX-8150 is a power hog could this be the problem? If so how could one remedy the situation when the extra 4pin power connector is not on the power supply?

Are there any other issues people have had where it did not post and it was corrected without having to RMA it? Just looking to get a general list of errors people have had so that all options can be exhausted before having to RMA the board.

I greatly appreciate any help.

You will not need the 4 pin plug unless you go more then 2 graphics cards. That is not the reason for the post problem. I do not have it hooked up on my board either. You will need to update the BIOS with a AM3 cpu so you can use the FX Chip. Just pick up a Sempron single core chip off of ebay for $25, flash the bios, then resale it. That is if you do not have one lying around.

Would that be a solid reason for it not POSTing?

I only ask not that I doubt you but I don't want to throw more money at it if indeed the board is dead. Like I said this build is completely new. My old computer was a Asus M2N-SLI with an AM2 processor so no comparability there.

I was aware of the possibility that I would need to get an AM3 processor to do a bios update I just want to make sure that its the reason its not POSTing before I go buy a cheap single core AM3.

Just so I'm clear if theres no LEDs that are lit next to the 24pin then it means the board is bad and needs to be RMA'd however if some of them are lit that means the board is fine and there is some other issue?

Could the culprit be the lack of an updated bios by just putting in the FX-8150 without doing an update from an AM3 processor first?

I just want it to POST

the 3 lights on bottom , the OC button power button and reset button , are they lit? Without turning the comp or mobo on , just plugging into Powersupply? If not they you're not getting power to the mobo which was the problem with my 2nd and would need to be RMA'd ,yes.
The LED's are error LED's that tell you what is causing the problem so if none are lighting up, either your not getting power or essentially, there's noting wrong with the mobo. I'm sure you've already tried but remove battery and try resetting CMOS with button via back , keep playing with it and if it doesn't work, RMA .

That's a possibility and if you could get an AM3 chip somehow to test it with you'll know for sure.
I'd hate to see you send the board itself back and discover it's the CPU or something else causing the problem. If you do have access to one for simple testing I'd do that first, if it POSTs then you'll know that's the deal with it.

I'm sure you at least know someone with an AM3 chip but if not, it's always helpful to have a backup chip - A 145 Sempron will work as good as any other AM3 chip for testing or as a backup plus those chips are cheap too. Have one myself and it's actually a decent chip to use for everyday stuff and it will even do some light to moderate gaming. Another plus is you may get one that unlocks = a dual core on the cheap but that's not guaranteed you know. Mine doesn't but it's still a good little chip.

Newegg currently has the 130 ( http://www.newegg.com/Product/Product.aspx?Item=N82E16819103944 ) and 145 ( http://www.newegg.com/Product/Product.aspx?Item=N82E16819103888 ) Semprons in stock so if wanting to get from them, should be no problem. If you can find it locally for around the same price I'd do that but I woudn't pay double for it.

Good luck and let us know if it works when you try it.

Having same problem with identical CPU/Mobo. I'm gonna go the route of running to Microcenter and picking up a cheap AM3 processor.

Not to necro a thread but I thought I would update. Everything is up and running finally. The problem did in fact end up being the bios issue. Used a Sempron 145 to boot up and update the bios, dropped the FX-8150 back in and its up and running. Now my sig is finally my real machine I'm running.
