» Drivers are a special kind of software that lets an app or apps talk to your hardware. And drivers are more prone to cause crashes and BSODs than anything else. Worse, they can be difficult, sometimes even impossible to remove/uninstall. That's why you should be careful while run an auto antivirus scan, clearing the wrong checkbox in Autoruns can break Windows *Permanently*.

As we know, files with .sys extension also belong to dll files, and its error is closely related to other dll files, therefore we introduce DLL Suite to fix this issue.

DLL Suite is able to fix sys file missing error, just because DLL Suite has built-in driver files, and it can replace the failure driver's file which causes the blue screen of death; it can also remove the virus/malware infection (such as PWS:Win32/Fareit)at the same time.

Click DLL Suite's Dashboard menu > Click Scan DLL Errors button > Click Fix DLL Errors button after the scan, and the blue screen of death or any other sys file related error will be repaired automatically. With the help of DLL Suite, it is much easier to fix BSOD and other errors due to the damaged .sys file.

    If you find it there, copy and paste it into the c:\windows\system32\drivers folder, then see how things work. If you can't find it in the dllcache folder, you can download one from my SkyDrive.

  2. STEVE HEDRICK replied on January 9, 2013: » A good idea before starting things is to first verify the integrity of your file system using the chkdsk command. From the command prompt window run the chkdsk command on the drive where Windows is installed to try to repair any problems on the afflicted drive. Running chkdsk is fine even if it doesn't find any problems. It will not hurt anything to run it.

    Assuming your boot drive is C, run the following command: chkdsk C: /r

    Let chkdsk finish and correct any problems it might find. It may take a long time for chkdsk to complete or it may appear to be 'stuck'. You should run chkdsk /r again until it finds no errors to correct.

    After running chkdsk, you would enter this command:copy c:\windows\system32\dllcache\compatt.sys c:\windows\system32\drivers

    Respond in the affirmative if asked to overwrite or replace the file. You should see a message that one file(s) was copied. Remove the CD and type 'exit' to leave the RC and restart the computer. You do not have to adjust the BIOS again to boot on the HDD since the CD will not be present.

    when you restart your pc, with the cd in the drive and bios changed to boot from cd, you should get a black screen with the words "press any key to boot from cd" if you are not getting this the cd will not run.

    auto run is not an issue, and if you were fully updated from Microsoft updates autorun should have been disabled. if the cd is not working, I am at a loss as to what to do next.
