"Why does my computer keep freezing up?" I was asked by a lot of people the cause of their pc free problems. And I am fed up with spending much time in answering the question time and time again. This article is to tell you the real cause of your PC Freezes.

Many people think it is the low RAM resource that results in the lockup problem. So they upgrade their RAM to 2 G, 4 G or even higher. But unfortunately only a few people successfully resolve the problem. Why? Because the shortage of RAM is only one of the possible causes that lead to only approximately 20% of the PC lockup / freeze problems.

The most probable cause of your trouble is the system problem – Registry Errors! That is the reason why people who already have more than 2 G RAM on their computers are still constantly bothered by the problem.

What is registry? It is the system database in which your most important system information and program settings are saved. It contains all the vital directive information for your Windows system. Your system needs to access the data in registry before it can execute a certain operation and process like system shutdown, restart, running a program, opening a file and so on.

But registry is easily corrupted and damaged when you are using your computer. Overtime, without proper maintenance, it will be loaded with errors and incorrect or even missing information which will make your system unable to work properly or implement a certain task. And when your system can not find the correct information, it will not know what to do. Then it freezes up! That is the real cause of your trouble.

How to fix the registry errors and stop your computer from freezing? You can download a good registry cleaner and install it on your computer. Then run a thorough scan in your registry. Your trouble will go away. And keep in mind that registry is easily damaged. You need to clean it up by running the registry cleaner once or twice a month at least, or you will have the problem again.
