Windows Vista system32\afc_os.DLL and NTVDM.exe errors

When I start up my computer (vista ultimate) I get a window with the following message "C:\Windows\system32\sfc_os.DLL is either not designed to run on Windows or it contains an error ". When I close this window (with difficulty) another window with "The procedure entry point sfc_os.SfcIsfileprotected could not be located in the dynamic link library sfc.dll" pops up. Behind these two windows is a window with "C:\Windows\system32\ntvdm.exe" with a prompt in it. I also get an error message " NTVDM.EXE has stopped working" and numerous other things that have stopped working.
Windows loads with a black screen and several programs with not open. I would appreciate any help.

 

Ok, I thought that might be the case. Thank you.

 

From a quick websearch, I SUSpect you have installed a program (maybe run a driver installer) that was made for a previous version of Windows.

Try to avoid reinstalling it again if you "nuke and repave" like Arie suggested. (Actually, [backup] nuke and repave is the way I like to recover after a catastrophe....happened once on my computer....happens more often on computers I am asked to work on... )

I just did a quick websearch, please don't shout me down if I am wrong. I just want you to be wary of the same thing happening again.

Thanks for the advise. I have nuked and repaved as you put it now I keep getting a "LOW DISK SPACE you are running out of disc space (NVCACHE(D" This disk has 500MB with 5.59MB free. The confusing thing is I didn't have this disk listed prior to the repave. Can you explain this for me please.

 

Sorry, it is an NEC Versa P8310 laptop, Windows Vista Ultimate 32bit,
processor: intel(R)Core(TM)2 Duo t77@2.40GHz,
RAM 2047MB,
Hard drives C:232GB, NVCASHE(D) 500MB????
That is all I know, hope it helps.

 

Thank you very much for trying. I have just gone into the Intel Turbo Memory and disabling ReadyBoost, rebooting the computer than enabling ReadyBoost again, this refeshed the Turbo Memory and solved the problem.

 

Good info, maybe it will be helpful for somebody else
