Win 7 won't boot past CLASSPNP.SYS driver

[Informative]

I've seen many questions about this error on many systems. My System is an old HP DL360 G5 server
Built in video went wonky all garbled on both VGA plugs
Installed a cheap video card to get around the failure and it is booting and looks fine except..
it hangs up at the CLASSPNP.SYS in safe mode and cant get past that point
Everything else on the system is good (HD memory cpu fans etc. all good)
reset the bios battery, tried reinstall windows, safe modes etc etc

I assumed at the point classpnp must be trying to talk to the wonky video device and hanging up there?
It's a good machine 3ghz multicore cpu and lots of miles left so of course I'd like to get it working again.

Ideas I have at this point include if there might be any replacement custom SYS driver file or other file
I could substitute for the funky one that hangs up the system or some way to tell win7pro to skip that file entirely?
Wasnt there a way to step through the driver file loads and confirm each one or was that an older version of windows and cant be done any more

Thank you greatly in advance to anyone who takes time to read and contribute ideas to this!

so I tried a different video board and with this old 2009 dx9 generation video card it was able to boot past the problem. system is working again. answer was it was a hardware failure and the classpnp.sys doesn't like some video boards and should be rewritten (doubt MSFT cares)

the solution for me is to start with the W7 advanced boot options

and use : Disable Driver Signature Enforcement.

afther this, dont shut down your win 7 simply hibernate.

I hope it`ll be useful to you
