A register is a very fast accessed area on a PC that can store information about the various commands that are performed by the computer. Some registers can be read only or write-only, and typically consist of a fairly small amount of extra storage. It is a good idea for PC owners to learn about how to recognize the different types of registers, how to use them, and how to clear them when the time comes for them to be erased.
When you look at a PC, you will notice that there are two main parts to the machine: the central processing unit (or CPU) and the system memory (also known as the RAM). The CPU is where your main computer processing happens, and is the one responsible for all of the computer instructions, while the system memory is where all of the data that is saved to your computer is stored. Typically, the PC operates much like an enormous book that is why it is so important that you understand how to control it properly in order to get the job done right. You can’t just tell the computer to start running, because if you do, it could possibly do something that will actually make your computer crash or have other problems. If you want to see what is happening inside of your PC, you should turn off the power, open up the case of your PC with a CD, and use your keyboard’s arrow keys to show all of the computer processes and then stop them one by one with the F-keys.
Generally, your PC runs Windows instructions, which are directives for it to perform different tasks. Instructions are commonly stored in the form of a series of numbers that are executed one after the other in a series called an instruction list. When these instruction lists are executed correctly, your PC will read them and follow them appropriately, which results in your computer performing the tasks that you want it to. However, sometimes these instructions can become invalid due to one of two reasons.
The first reason why a CPU register may become invalid is if the memory of your PC has become corrupted. This happens more frequently with PCs that have a common registry problem, which is when a lot of redundant, leftover information can build up inside your PC’s main memory. Sometimes this leftover information can cause your computer to have a performance issue, freeze up, or even die. To fix this, you will need to clean up your registry with a registry cleaner. However, not many people know how to do this safely, so here are some tips on how to do it.
The second reason why your CPU register can become invalid is if a program accidentally erased one of the two accumulators that are located inside of it. The accumulator is what Windows uses to track how many instructions your PC is executing at once. When this accumulator becomes corrupted, there is nothing that prevents your computer from temporarily shutting down or crashing. These two accumulators, referred to as the branch accumulator and dynamic accumulator, track instructions separately and are crucial to Windows.
The third reason why your register can become invalid is if it was written to by a hardware device such as a USB drive, floppy disk, or inkjet printer. Not only can these devices leave behind instructions that result in the wrong function of your CPU, but they can also cause your computer to execute instructions that aren’t suppose to be executed. To fix this, you will need to clean up your registry with a registry cleaner. This will prevent future problems from occurring due to invalid instruction executions.
