Story of my Desktop

I recently upgraded my GPU to ASUS GTX970. After installing the GPU, I tested it by playing games and I felt confident that the GPU was not defected. From there, I decided that it was time to revert my desktop from Windows 10 back to Windows 7 (I don't like the blocks) and has since been reformatting my desktop over and over.

Initial attempt:
1)Inserted Windows 7 Home premium edition into DVD drive
2)F8 and deleted all old partitions and created a new one
3)Stuck on “Window Expanding Files” at different percentage of recovery
4)1-10 attempts later I managed to have desktop reformatted
5)Installed mobo, and gpu drivers and desktop started freezing up
6)Started another reformat session

Current attempt:
1)Inserted Windows 7 Home premium edition into DVD drive
2)F8 and deleted all old partitions and created a new one
3)Stuck on “WindowExpanding Files” at different percentage of recovery
4)1-10 attempts later I managed to have desktop reformatted
5)Installed mobo, and gpu drivers
6)Tried installing Windows 7 updates and ended up with “Reverting update changes”
7)Windows would now boot straight into Bios and when I “Save changes & exit” windows would just restart and boot to BIOS again and again.

I’ve searched online about this problem and have had no luck. Help save my desktop!

Questions/Assumptions:
1)How could I tell if Window 7 disk is corrupted/bad?
2)Is GTX970 not compatible with my other hardware?
3)My SSD is dying?

MY Desktop Specs:
CPU: i5 4690k (1 year old)
MoBo: Asus Z97a (1 year old)
GPU: Asus GTX970 Strix (Brand new)
SSD: OCZ 228G (1 year old)
Asus DVD drive

Thank you!

Hi and welcome to SevenForums,
Have you restored your bios to optimize defaults ?
Make sure Boot/ CSM is enabled and also not set as uefi only ?
Also if secure boot is disabled if available ?
