dx79to windows cannot start after overclocking attempt

[IKaga]

Dear Community, please help.

I tried to overclock my system and messed up with some settings. Did a mistake obviously.

System didn't boot.

1. I put the settings back as was - tried different combinations without OC

2. I reset the Bios profile to default.

3. Tried to boot with different bootable Windows HDDs and SSDs

4. I flashed a newer Bios version

5. I took all RAM out and put only one inside

Always same unknown error on start-up -> during the animation of the windows logo.

System:

Motherboard DX79TO

i7 3930K

32GB RAM (G.skill Ripjaws Z, DDR3-2133 CL11-11-11-31 1.50v 8GB x 4)

Geforce GTX 780

PSU Enermax Liberty 500W

(tried different SSDs and HDDs)

Hope you've got a suggestion for me! Thank you!

I understand your system POSTs but crashes during operating system boot process.

It would help sharing the operating system version and exact verbatim of the error message.

When you tried to boot from other SDD/HDDs, was the operating system already installed or are you trying to install it?

Just a suggestion on something to check: O/S boot failures can be caused by an incompatible Chipset SATA Mode. For example, installing the O/S with the mode set to AHCI and then trying to boot it with the mode set to IDE (or vice versa).

Hello Scott,

thank you so much for the help. You are my hero today! I really thought buying a new system to be able to work today - but you saved my day! Thank you!
