Replaced motherboard, unable to install Windows or partition HDD

[hamburglar]

My mother's computer recently had the integrated graphics card died. I replaced the motherboard with the exact same model and part number and I'm now trying to reinstall Windows 7.

When I boot from the Windows 7 installation disc, it loads to the screen where I can select the language, and then the choice of either "install now" or "repair your computer." I first tried loading the repair option, as I need to clear the C drive and create a new petition. That just sat there loading for hours and never did anything. I then tried the "install now" option, and the "setup is starting" always just sits there loading, but never actually does anything. I have also tried hitting Shift+F10 to get to the command prompt and loading DISKPART to try partitioning he hard drive that way, but it just hangs and never loads or allows me to input any more commands.

I have tried changing everything in the BIOS, from completely disabling the floppy drive (which the computer doesn't have), disabling onboard LAN and audio, and switching between AHCI and IDE for the SATA type. I have also tried changing between PCI-E GPU and Onboard Graphics, since the computer only has an integrated GPU right now. Basically I have tried every combination I can think of.

What can I possibly do from here to resolve this problem?

Why didn`t you just install a video card ?

Set the bios to defaults and try again.

There`s no reason diskpart shouldn`t work, last resort, make and use a Partition Wizard Boot CD to format and setup the drive.

Is there a secure boot option in the bios ? Is it disabled ?

I was told by someone who knows much more about this than I do that if I just added a PCI-E GPU and the integrated graphics had died, then the BIOS would fail to post.

I have tried setting the BIOS to defaults, no luck.

I don't see any options in the BIOS for a secure boot. The only thing slightly similar to that is an option to display diagnostic statistics when booting.

Make sure you have all the cables connected properly & they are fully seated.

Enter the BIOS screen & see if your hard drive is showing up in the list of bootable devices.

Everything is plugged in. I made a bootable Partition Wizard disc and tried wiping the HDD, but it froze during the process. Then I tried booting again from the Partition Wizard Disc and when it came to reading the HDD at 3.0 Gbps, it said something like it was misrepresented or misallocated. After failing two more times, it tried limiting the SATA connection to 1.5 Gbps but it just would hang. Now the BIOS doesn't even recognize the HDD and it is making clicking sounds. Not the random sounding clicks you would hear from the HDD being read, but louder, more rhythmic clicks. I think I might have fried the HDD now.
