I have problem with cng.sys and bluescreen of death on my windows 7 x86 Ultimate.

Once I just restarted my pc and all went wrong. I have tried all memtest and deep malware scan and still nothing..everything seem to be fine. Even registry repair seem to be fine.

I have tried to repair while boot from cd and still nothing. I don't know what to do...

I have windows 7 ultimate x64 on other partition and that version is working perfectly and I don't know how is that possible if other version is not working.

Here is my screen:

Please help!


This is my F8 screen:

Since this issue is presented at startup, you can try Startup Repair which repairs most startup issues. To access this tool, restart your computer tapping on the F8 key until you reach the Advanced Startup Options menu. Select Repair Your Computer and then Startup Repair. SFC scan is also a good tool to repair missing or corrupted files. If these steps don’t fix the problem, restart your computer and boot to the Advanced Startup Options menu. This time select Disable automatic restart on system failure. Try to reproduce the problem as you described in your first post and report any error messages. Let us know if this helps.

Hi I forgot to mention that I have tried everything from above.. nothing seems to be working. Safe mode, and all other things doesn't work. The windows logo is starting and it freezes and shows bsod and restarts. – user123_456 Apr 12 '12 at 19:01
and I don't have startup repair option – user123_456 Apr 12 '12 at 19:02
I have uploaded photo from the F8 screen – user123_456 Apr 12 '12 at 19:18
See if you are able to boot to the command prompt. If you can run the chkdsk /r command and I would also scan the computer for malware. – Jeff Chilton Apr 12 '12 at 19:54
If the Windows folder which hold of the of the important system files and drivers is corrupted then it looks like that the installation of Windows 7 on that partition is corrupted as well and Windows 7 needs to be re-installed to resolve this issue. – Jeff Chilton Apr 12 '12 at 20:41
