There are many factors causing ntdll.dll crash in WIndows.
Hardware failure could be one of them.  Please check your harddrive for file allocation errors and/or bad sectors and memory errors.
To check for hard disk errors (This may take hours)
Open Computer by clicking the Start button , and then clicking Computer. 
Right-click the drive that you want to check, and then click Properties. 
Click the Tools tab, and then, under Error-checking, click Check now. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
To automatically repair problems with files and folders that the scan detects, select Automatically fix file system errors. Otherwise, the disk check will report problems but not fix them.
To perform a thorough check, select Scan for and attempt recovery of bad sectors. This scan attempts to find and repair physical errors on the drive itself, and it can take much longer to complete. 
To check for both file errors and physical errors, select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors.
Click Start.  The Check will start automatically when you restart Windows.
To check for memory problems
Open Memory Diagnostics Tool by clicking the Start button , and then clicking Control Panel. In the search box, type Memory, and then click Diagnose your computer's memory problems. If you're prompted for an administrator password or confirmation, type the password or provide confirmation. 
Choose when to run the tool. If you choose to restart your computer and run the tool immediately, make sure that you save your work and close all of your running programs. The Memory Diagnostics Tool will run automatically when you restart Windows.
