Computer not reading hardrive

So i have tried the following.
Switching SATA ports.
Switching SATA power/data cables
switching from ide to achi
Tried a different hardrive with different cords and differend ports.

The problem I am having in more detail.

I came home from work and noticed that my computer had been powered down abruptly and since then its acting like it cant read my hardrive. I tried using windows 7 install disk to reformat the hardrive and noticed its not even showing up as a hardrive for me to format.

Clarification Request
what model computer, make?

Know the exact motherboard model? IDE hard drive? Need to use SATA driver files on a floppy to boot it? Been in BIOS and tried IDE compatible for SATA?

The motherboard is asus p5q pro the hd is Seagate 1TB Desktop SSHD SATA 6Gb/s 64MB Cache 3.5-Inch Internal Bare Drive. Its a custom built computer, also note that his is a brand new hd i bought due to my old 1 not working. My old hd i tried was a western digital wd 1600 AAJS

SSHD is a Hybrid
Hybrid Drive Information

Did you use the maker's software first to setup the drive to accept installation of operating system?

Food for thought

I am thinking my motherboard is bad but not really sure how to check any advice?

The thing is.... Seagate.

I would need to test this drive on some other PC or USB to SATA case/cable.

while in bios

was the system clock right in bios? if not, then possibly the motherboard batter needs to be replace.

good idea

or at least short the CMOS, but batteries are so cheap. CR2032 for most motherboards.

can you see your CD/DVD drive?

Are you about to boot any bootable disc from the CD/DVD drive, when you choose that drive to boot from?

I just plugged in the 2 hard drives to my other computer and both hard drives are showing to working correctly. Also note on the broken computer my dvd drive is showing up just not my hd 1/2 the time. Kinda weird it will show up sometimes in bios and then disappear.

change the data cable

Maybe change the power cable too. Also use a different SATA plug and avoid the white and orange ones

So i just rewired entire computer and for a second i thought i had it. Only to fail once again. Here is what i did.

Tested both HD's on 2nd computer

Installed win 7 on hd #2 seagate (Brand New) HD#1 had it installed seeing it was my original hd for this computer.

Rewired HD#1/2 with new SATA data/power cables.

Set it in BIOS to boot off HD#2 (Seagate)
Rebooted after saved config its on IDE Compatible

After this it got stuck on windows screen for like 5 mins then i rebooted it. After rebooting BIOS is no longer even seeing the 2 hard drives and is only reading my dvd drive.

Did you also install

....the driver files for that particular motherboard? Each motherboard has controller chips on them which needs driver files that are particular to them. You find them at the manufacturer's site, they won't be on the windows disc.

You install windows first, which puts generic driver files which allow enough access to then add the necessary driver files to make the motherboard run fully capable.
