Have you ever seen Windows XP blue screen? I believe all XP users might have encountered blue screen during the computer life. So, do you know what causes a blue screen? Here, we will learn both from hardware and software to see the causes and how to fix XP blue screen of death.

Part One: Hardware
First, excessive overclocking may be the main cause for XP blue screen for it will result in overloading algorithm and CPU overheat, which causes system operation errors. If you want overclocking without a blue screen, you’d better to take some steps to dissipate heat quickly such as turn to use a powerful fan and add some heat-dissipating materials (like silica gel). But it is recommended to keep the right amount of overclocking or no clocking in order to avoid blue screen of death. In my opinion, a stable PC performance is much more important than a short-tern high running speed.

Second, a physical damage on the memory module will also cause a XP blue screen because of the incompatibility. If so, please buy a new memory module to solve the XP blue screen and optimize PC performance.

Third, (if you have ever noticed) you will find that once a loading CD is opened abnormally, the computer will also come into blue screen. This will not influence the proper running of the system, but please inject the CD or press “ESC” key to solve the problem.

Fourth, another fatal cause is hardware conflict. So please go to Start menu -> Control Panel -> System -> Device Manager. Here, please check whether there is any device marked with yellow exclamation mark. If so, you can first delete it and then reboot the computer, letting the system automatically adjust the settings. If it does not solve the problem, you can manually adjust or update the corresponding devices.

By the way, please note that some inferior parts and components will be another cause for XP blue screen. So please be careful enough when buying CPU, memory chip and other components from the market.

Part Two: Software
From software, there are many parts will result in XP blue screen as what you can see below:
1)The computer is attacked by virus or hacker; 2) there is some error/ loss in the Windows registry; 3) too many programs run at windows startup; 4) versions conflict; 5) not enough virtual memory; 6) necessary DLL files lose; 7) excessive character files, etc. At this point, after learning the causes, it is possible for you to figure out the XP blue screen within proper solutions.

With the discussion above, you will find some methods to fix XP blue screen of death. But please remember to timely quit programs that do not need currently to save system resource and release more available memory. Beside, please do not forget to periodically clean up the system and defragment hard disk in order to always optimize PC performance.
With the above solutions and good habits in suing computer, you can easily avoid and fix XP blue screen. Please do not forget some tiny tips when trying to optimize  PC performance.
