During the usage of Windows XP, it is inevitable that you have ever received kinds of read / write errors such as “xx memory can not be read or written”. So what should we do to effectively straighten them out and avoid the same problems when running large applications or games in the future? In fact, when unfortunately encountering the above problems, you can easily follow the steps below to solve the problem to optimize PC performance.

1) Remove some invalid plug-ins. When surfing the internet, some plug-ins will automatically install on the computer without letting us know. Seriously, some will be very easy to conflict with other applications, which indirectly results in system memory read/ write errors. In order to optimize PC performance, and provide a clean, stable working environment for the large applications and computer games, it is recommended that you can regularly run security software to check whether there are invalid plug-ins on the computer and timely remove them from the system.

2) Manually restore system services. If there is something wrong with the service “Windows Management Instrumentation”, a system memory read / write error will also occur. So you can manually restore this service in order to optimize PC performance. You can exactly follow the step below: go to Start ->run ->type “services.msc” to access “Services”. Here, please locate “Windows Management Instrumentation”->right click it to select “Properties” ->click “Stop” in the popping-up General tab to temporarily disable this service. Then please open system manager and then open the below folders one by one: Windows->System32->Wbem->Repository, and back　up all folders within “Repository”. Last, please reboot your computer and restart “Windows Management Instrumentation” service.

3) Repair corrupted system files. Once the computer is infected by viruses, some files will be removed incorrectly, which results in memory read / write errors. So a repair of the corrupted system files is needed. What you need to do is to run an anti-virus program to check whether the computer is infected by viruses or spyware and turn on the real-time safeguard to protect your computer at any time.

Then you can use the “sfc” demand to repair the corrupted system files: go to Run -> CMD to open the “Command Prompt” windows -> enter “sfc/scannow” and press Enter to proceed the scan process. Once there is a corrupted system file, you will be promoted to insert the Windows installation disc to replace the corrupted files.

4) Last, to avoid this problem, what you need to do vitally is to release more available memory. So when running large application, you can first turn off other running program expect the one that you do need. Besides, please do remember to timely uninstall the unwanted programs that you do not need to release more available memory. Moreover, you should run a Disc Cleanup to regularly clear the useless system junk files from your computer, which followed by a simple disk defragmentation. In this way, all files will be arranged coherently on the hard disk and easier to be accessed to, which will not only fix the memory read or write errors but also optimize PC performance.

In conclusion, with the simple steps above, you can easily fix the read / write errors and then optimize  PC performance greatly. But please note that no matter how brand-new your computer is right now, if it lacks proper daily maintenance, it will not work properly for you.
