Scenario: I recently bought a new motherboard after my last one fried and the whole PC boots up and appears to be working fine, the only problem is the system wont recognize any of my hard drives, I tried two different power cables with my hard drive, on one of them the drive would spin up, and on another it wouldn't even attempt to spin up, I have tried two hard drives and I know one of them definitely works, but they both behave the same way, I have tried multiple Sata cables and connections and multiple power connections but it's still the same result so far, any help would be greatly appreciated

Here's all the specs.

Asus Sabertooth X58 Motherboard
Seagate Barracuda 1.5 TB HDD
PSU - Corsair TX750 w
geforce gtx260
3- 2gb sticks Corsiar RAM DDR3
CPU is an Intel i7 Dual processor, don't know the exacts on that.
OS: Windows 7 Home Premium 64x
 
OK firstly check your SATA configuration in your BIOS
Secondly if thats set correct, can you see the HDDs in the BIOS just not able to boot from them? or are they not visible in BIOS either?
 
Okay, to be honest, i don't know if it's IDE, RAID or AHCI (well i know its not IDE...but meh who knows anymore, those are my only options). I tried em all, either way it just doesnt see the drive, its not visible in Bios.
 
Honestly, I know to use a SATA cable, the proper power cable (not that its rocket science but just getting the obvious out of the way), but as for what configuration (IDE, RAID or AHCI), don't know what i should even configure it as..it was IDE by default. But I tried all three, made no difference what so ever.

And right, Bios doesn't even see the HDD. And I did check connections, nothing loose and no reason it shouldnt at least see it.
 
Can you tell if the disk is getting power through testing vibration on the HD? Does it stop at a screen where it says 'NTLDR is missing'?
