During using computer, if such accident happens, it is really a disaster for those beginners. But, do not worry. If you have learned the radical causes of blue screen, it may not be a problem for you any more. This is what I want to introduce to you in this article.

In fact, blue screen problem is mainly connected with memory capability, CPU frequency, CD-ROM, hard disk fragments and so forth. Since many reasons account for computer blue screen, I would like to explain some of them from the aspect of hardware. That is how to solve blue screen caused by hardware problems.

The low virtual memory leads to algorithm errors of system multitask.
Virtual memory is a special method that is designed for solving insufficient system resource in the Windows systems. Normally, it requires remain space in the hard disk is two to three times than that of physical memory. However, some computer fans would like to cram excessive stuff into their hard disks in order to make full use of them and turn a blind eye to the rigorous requirement of Windows that there should be enough disk space to support virtual memory. Therefore, due to low hard disk space, virtual memory can not run correctly and is troubled with algorithm errors which result in blue screen probably.
Well, it is rather easy to deal with such problem. You are supposed to delete the temporary and swap files produced by system and not to put too many files into hard disk so as to free up disk space. Or you can configure virtual memory manually. You can change the default address of virtual memory to other logical disks. In this way, computer can shun blue screen caused by insufficient virtual memory.

There is too small available disk space or too many fragments.
Generally speaking, the available space in the hard disk should be above of certain value, since different systems require values differently. Otherwise, the blue screen problem is likely linked to the size of available space. In addition, if there are too many fragments in the disk, it can lead to blue screen easily. Therefore, it is necessary to defragment disk at proper intervals.
You can turn to Windows defragmenting program, of course. But, if you want to speed up defragmentation and protect hard disk as well, I recommend you to use special defragmenting software called “Advanced Defrag”. You will satisfy with this program for sure.

CD-ROM is opened abnormally when reading disk.
Blue screen happens when the CD-ROM is reading the disk and is being operated mistakenly. But, such problem has little influence on system running. What you need to do is to use CD or press ESC. And everything is OK.

All in all, since blue screen can resulted from many reasons, you should protect your computer in all-round way and improve computer knowledge as much as you can.
