Find out if the issue is with the OS or hardware.

There is only one way to determine if the issue is hardware, and that is running hardware diagnostic tools from the systems vendor, or manufacture.

There are two ways of looking at the OS.

The first is to look at the event viewer and determine if there is an issue.

After determining the corrupt or missing file on the OS. It is now time to start replacing the file.

A common issue with the file system is the autochk.exe file in the system32 folder. Determine if it needs to be replaced by typing the following sfc command.

"sfc /VERIFYFILE=c:\windows\system32\autochk.exe "

Find a replacement for the file from another system to take it from, or find a copy somewhere else.

Then take ownership of the file that is going to replace with the following takeown command.

"takeown /f \\.\c:\windows\system32\autochk.exe "
Give user rights to the file by using the following cacls command.

"cacls \\.\c:\windows\system32\autochk.exe /g admin:F "

Rename the file by using the following rename command.

"ren \\.\c:\windows\system32\autochk.exe autochk.exe.old "

Lastly, move the new file in the location of the old file.

NOTE: If this does not work, reboot into Safe Mode command prompt, or use the OS System Recovery CD command prompt.

Step Four:

Reboot and go back to step one.
