When using the Windows XP operating system, we will inevitably encounter a variety of errors and problems. At this point, what we have to do is not "hands-on", but to know how to troubleshoot and how to solve the problem. Now let's analyze what is the main cause of the Windows XP operating system failure, and how to solve these problems. 1. Failure caused by third-party software Some software programs are not well written. Windows XP settings are modified during installation or uninstallation, or normal system files are deleted by mistake, causing problems with Windows XP. There is also a compatibility problem between the software and the Windows XP system, software and software. If there is a software conflict or compatibility with the system, just quit or uninstall one of the software; if the anti-virus software is not working properly, you can try to turn off the anti-virus software monitoring function. In addition, you should be familiar with the settings of the common tools you have installed to avoid unnecessary false failures. 2. Virus, Trojan, and malicious program intrusion caused by a number of malicious programs, viruses, Trojans will force the system through the webpage, bundled software installation or secret room to invade the user's computer, and then forcefully modify the user's web browser home page, software automatically Startup options, security options, etc., forcibly pop up ads, or make other actions that interfere with user operations and consume a lot of system resources. Caused various errors and problems with Windows XP. For example, unable to access the Internet, unable to enter the system, frequent restarts, many programs can not be opened, and so on. To avoid these situations, we'd better install 360 security guards, plus network firewalls such as ZoneAlarm and virus protection software. If you have already taken the initiative, use anti-virus software to kill and repair the system according to the method described in the article. 3. Misuse, optimization, clean up Windows XP too much If you are not familiar with the system, it is best not to modify the Windows XP settings. If you use the optimization software, you should use the system setup backup function that comes with the optimization software to back up the system settings and then optimize the system. For the problems that have already occurred, you can take a look at the "Brief Brief Basic Solution Routine" and the case below to find a solution to the problem. 4. Using the folk modified Windows XP installation system, there are a large number of folk modified Windows XP systems and GHOST Windows XP systems. These simplified and modified Windows XP generally delete some system files and streamline them. Some functions, some even integrated Trojans, viruses, and system backdoors. If you install this type of Windows XP, security is not guaranteed. It is recommended to install the original Windows XP and patches. 5. There is a problem with the hardware driver If the installed hardware driver is not certified by Microsoft WHQL or the driver is not well written, it will cause Windows XP failure, such as blue screen, inaccessibility to the system, CPU usage up to 100%, etc. If you can't get into the system because of a drive problem, you can go into safe mode to uninstall the drive or reinstall the correct drive.
