Windows 7 will not boot after reseating CPU; BIOS does not recognize Windows

Hi, so I recently upgraded my video card and heatsink in my gaming PC and am having a peculiar issue with my computer. After installing a new heat sink and video card, and reseating the CPU, my BIOS will no longer recognize that Windows 7 is installed on my SSD. Every time I boot I get the "Reboot and Select Proper Device or Insert Media and Press a Key" message.

I have gone through my BIOS and changed the boot priorities as well as run windows recovery/repair. While running the recovery, I have ran a chkdsk on the drive and it found no bad files. The recovery disk does not recognize a version of Windows either, but when I check the directory of the drive Windows is still present. I have also reset the CMOS to no avail.

Does anyone have any troubleshooting ideas that I could try to solve this issue? I'm all out of options and have tried to search forums but none of the techniques I have found have worked for me.

My system is:
CPU: Phenom II x6 1055t
MOBO: Asus M5A97
Heatsink: Corsair H100i
GPU: Gigabyte GTX 760oc 2GB
RAM: 8GB of Kingston PC1600
SSD: Corsair Force 3 120GB
PSU: Antec HCG 620w

Thanks, I really appreciate any help.

  1. Nice! I recently ran into the same problem with a Corsair GT.
    Tried everything you mentioned.
    Solution = get Corsair SSD toolbox select erase and re-install windows.
    Might not be what you're looking for but it worked for me.
  2. It's likely related to the boot drive as you know already.

    Since you've already booted previously, my guess is something like a loose SATA DATA cable to the drive.

    I've checked the SATA cables, even changed them and swapped SATA ports on the MOBO, no luck. Tried the power cables as well.
