New build, No POST/boot

Hello there, recently aquired all my parts needed and built my new basic PC, However when I went to turn it on only the Led of the power button, and then later the led fan came on (then started flashing after I made sure everything was in the right slot) I take everything out and do the "mobo on a box" method and in which the PSU fan, CPU Fan and the GPU fan (when I had it inserted) span and nothing else, no Beeps, no message on screen.. Nothing.. perhaps the little speaker thing is broke. I mainly suspect it to be either the CPU or the Mobo itself..

The PSU appears to be fine as I plugged it into a older PC this morning, but I can't do the same with the cpu or ram since they are different makes and generations, (spare PCs are Intel based and use DDR2 ram)

So that leaves it down to the CPU, the RAM and the Mobo.

I take out the ram and turn it on expecting to here the annoying no ram beeps but nothing...

I've also heard that CPUs are the last thing that's expected to be wrong so thats another point towards the mobo.. I don't have any spare AM3+ CPUs or Motherboard nor do I know anyone with any, and I don't want to be charged enormous amounts of money to take it to a store (The only one nearby I can think of is PC World, and I don't think anyone would like to take their PCs there...)

Am I on the right lines? Anything else I should do?

Also if there happens to be anyone in the Southampton area that has an AM3+ CPU/Mobo I'd love to use them for 5 mins to test mine P

Parts are ASROCK 960GM-U3S3 FX
FX 4170
Stock Cooler
Sapphire HD6850 2GB DDR5.
Crucial CT102464BA1339.M16 8GB X2
250GB Barracuda HDD Sata 3
Corsair 430CX V2

 

I've done that a few times to no avail.

Gonna try everything one more time and if nothing then I'll have to bite the bullet and have to pay out of my own pocket to send the mobo back.. (which is annoying)

Edit, Yup, something is definitely borked... Just wish I had a way of knowing..

Edit 2, Emailed a local repair store and they said they'd charge £55 just to look at them... Yeaaaaah no.. that's more than the motherboard cost!

 

Small update, got a new motherboard (Still working on getting the original sent back but a few complications got in the way) and still nothing which must mean the CPU is dead which is mega frustrating since it was bought a couple of months ago so no return...

I'm assuming a dead CPU would stop it from beeping even without the ram installed? or perhaps the speaker that came with the case is also broken..

I mean at this point it can only be the cpu's fault..

 

Well I recently found out the CPU is infact a OEM model (of which I don't think it was advertised as such but can't check up on it since the seller left and the page no longer exists which of course is very fishy) the seller is a very aggressive person who claims I'm lying so even though It's an OEM model I've contacted AMD just in case, i'll at least get their opinion on the matter..

But no more updates to share besides the fact I still seem to be the only person in southampton that has an AM3 (am3+ or otherwise) that or no-one I've contacted is nice enough to let me borrow one to make sure everything is working.. perhaps after I've sent the asrock mobo back I'll just have to contact a repair store and negotiate with them.

 

Sorry for the double post but this will serve as a bump and an Update, I got another CPU ( An FX 6300) and still nothing, I'm completely out of ideas..
