Recovering original bios after upgrading wrong one!

HP Recommended
hp dc7700 minitower
Microsoft Windows 10 (64-bit)

Hello,

 

I recently installed the wrong bios version for different desktop model 786E1 and I had a problem with the cpu fan which became loud and noisy!

 

I did the upgrade because I had microcode error after installing a different CPU "core 2 duo" , so I want to rollback to the correct bios version by downloading full bios file with the correct version that was working for my PC

 

786E bios ver 1.05 Rev. A

 

All available versions are just microcode updates so I can't find full bios file, all are just 65 kb size!

 

Any help is appreciated.

Hello
then I can just indicate where to find other versions!
On the one hand, it is rather risky to try to go back, sometimes impossible.
And I can't guarantee anything
In addition it may not change kidney problem
So it is at your own risk!
for other update, there is no laugh under windows 7, it is necessary to modify the version of the system here:
