What is the cause of the beating?

There are cases when some computers have very bad or poorly built memory and if it is being accessed every time at a very low speed then the computer swaps data in and out to accommodate the file or application that you are running and it also needs the memory space. it is called Thrashing. Usually RAM figures out the process of thrashing because it is a part of the computer that holds the data you are working on at that particular moment or time. The Operating systems uses a technique called Time Slicing. Time slicing means that your computer gives a specific amount of time to each of the application you are running. This amount of time is in nano seconds and that is why we hardly notice it. You would be able to solve this problem by increasing the system RAM or try to perform one application at a time so that there is less swapping to be done.

Ntbootdd.sys is actually a duplicate copy of SCSI driver that is being used to compensate SCSI driver if it has been disabled due to some sort of error. If the windows isn't able to boot SCSI drivers then this file comes into action to replace them and handles the boot process.
