BSOD Error 0x0000007b

Computer spec:
Dell Optiplex 9010 Core i7
Windows 7 Professional 64-bit
8GB RAM

My PC stuck on start-up screen (starting windows logo ). I tried to repair it but windows repairing failed. Then i use system restore, after that system work when i again restart the system it again stuck at start up screen (starting windows).

I run the SFC /SCANNOW after finish it say it can not fix some errors.

I also tried fixmbr, fixboot and bcd but nothing happened.

I install hp printer driver after that this thing happening.

I again use the system restore after successful boot, Advance system care and Malware and anti-malware
but system is clean.

I reinstall the HP printer driver and again uninstall them. After i restart the system which give me BSOD screen error "process1_initialization_failed 0x0000006b".

I tired to enter into safe mode but at that "classpnp.sys" the BSOD come again and restart the system.

I search in google and find that you have to rename classpnp.sys or copy, so i copied it from another dell system. After that it BSOD error change (I attached image of BSOD).

When i run SFC /SCANNOW "it say it could not fix some errors". I run the scan 3 times.

Minidumps are not created in my system. I also change the registry keys still it is not created.

Safemode is also not working.
