ASUS H110M-K and classpnp.sys (0000007b error) hangs Windows7 whille loading

[TomJFD]

Hello! I've changed my old motherboard and CPU to new ASUS H110M-K with newest BIOS and Pentium G4560.
On my Goodram CX300 SSD I had installed earlier Windows7 which I used with the older motherboard.

When I updated motherboard and CPU and connected the SSD with Windows7 I got BSOD telling me the error 0000007b (problem with classpnp.sys).

The problem is with the disk controller in Windows7 which I believe is not compatibile with ASUS H110M-K which only supports AHCI (I cannot switch to IDE or SATA).

Tried everything, renamed classpnp.sys, updated to newer version, tried to boot from Windows Repair Tool (restore points, system repair, startup repair, fixing mbr in command prompt etc.) and nothing helped.

I know that Windows 10 installation would help, but I dont lose the data, passwords and software installed in my Windows 7 (upgrade from Win7 to Win10 only possible via Windows and not from the USB stick).

Thanks for the help.

Kind Regards,
Tom

ASUS H110M-K needs BIOS version 3016 to use a Kaby Lake Pentium G4560. If the BIOS has not been updated by you to that version, then you need to use a 6th Generation Skylake CPU to get the motherboard working. A Celeron G3900 is about $45.

If you are attempting to use a previous OS installation from another PC, I doubt that will work at all. You need to do a new installation of the operating system.

Hello, thank you Calvin for your answer.
Yes, the BIOS is updated already and it handles the 7th gen Kaby Lake processors (my Pentium G4560).
I recently found many people that managed with this error but in my case their solutions won't work.

I dont know what to do with my 5-year old Windows 7 with all the data from Mozilla, saved data from games etc...I thought it will no problems when connecting the SSD with Win7 to new motherboard and CPU. If I only could upgrade it to Windows 10 it would be great...

Maybe I can connect the SSD to friend's computer to make my Windows 7 load so then I can update it to WIN10 and finally I connect the SSD with Win10 to my new PC...

Connected the SSD with Windows 7 as master to my friend's PC who also have Win7...the same problem, code 0x0000007b while loading OS.
Scanned whole disk for viruses/malware and nothing. Also swapped classpnp.sys from his Windows to mine..and nothing 🙁
