How to recover data from a crashed computer

Computer crash is a very common for us.  However, many people do not know exactly why there is a computer crash. Once the crash happen, it usually shows as "blue screen", and then the system can not start.  Now I’d like to introduce what are the causes for computer crashes.

First, Computer crash caused by hardware

1.  The board capacitor. Sometimes, other computer hardware is good, but it will always crash  when boot. It may for  the bad capacitor of motherboard.

2.  Poor heat dissipation. The monitor, CPU and power will produce great heat in the work. Hear dissipation is very important. The overheating of the display will cause distortion of colors and pictures, or even shorten the life of display. The long working hours can lead to poor heat dissipate of power or display, then cause computer crashes.

3.  The inappropriate movement of computer. The movement may intensively shake the computer, which lead to the loose of inner parts, causing imperfect contacts then cause computer crash.

3.  Dust. Too much dust in machine can cause frequent crash failures. If the floppy drive head or the laser head are contaminated by dust, it’s easy to have a  read and write errors, or even cause serious computer crash.

4.  The devices are not match. For example, the motherboard processor frequency and CPU frequency does not match. The old motherboard overclocking while the FSB setting is too high. That may influence the stability of operation, resulting in the crash.

5.  Memory failure. The main causes are memory loose, weld or memory chip quality. You should exclude these failures based on the situation. If it is the memory quality problems, you need to replace one.

6.   Hard disk failure. This is due to hard disk aging or improper use that cause bad tracks, bad sectors.  So when the machine is running, it is prone to crashes. If the problem is serious when you check, you can only change a hard drive.

7. CPU overclocking. Overclocking can improve the work efficiency, but also can cause the instability of its property. Because the data writing and reading speed are depends on  the exchange speed of data between memory and hard disk. Overclocking results a more serious  contradiction between them.

Second, Computer crash caused by software upgrading

1.  The virus infection. The virus can reduce your computer work efficiency, resulting in frequent crashes. In that case, we can use the antivirus software to kill virus.

2.  The software improper upgrading. Many people may thought that the upgrading will not be a problem. But  they do not know when the software is upgraded, some components are also upgraded. However, other programs may not support the upgraded components so that leading to various problems.

3.  Illegal uninstall software.

You’d better not to directly delete the directory which contain the software. There may be a lot of garbage exists  if you directly delete the directory. The system will become unstable over time so that crashes happen.

4.  Too many start-up programs. These programs may take up too many system resources which lead to the needed data for some programs appear error in memory.

The frequent crashes will greatly affect the progress of our work. And if t computer crashes happen when it is writing important data, the unsaved data will be lost. That may cause great inconvenience for us. Therefore, we suggest you to know the specific causes for computer crashes. And if you have other problem in data recovery, you’d better ask Hdata recovery specialists to help you.
