Have you ever noticed that you are using a slower computer due to the 100% occupancy of CPU resources? Normally, there are many possibilities which result in this problem like hardware, software, and viruses. However, in this article, we will discuss solutions on how to increase computer speed easily by yourself when 100% CPU occupancy.

1) Turn off unnecessary monitoring services
Some new-editions of anti-virus program will add features to randomly monitor the WebPages, add-ons and emails, which undoubtedly increase the system burden. Now, even though there is not a reasonable way to solve this problem, it is recommended to turn off some unneeded monitoring services to avoid malfunction caused by anti-virus programs, or upgrade your hardware to increase computer speed.

2) Use certified drivers maximally
Nowadays, a large amount of test drivers flood on the Internet, which increases the harder to discover the malfunction cause and results in 100% CPU occupancy. So it is suggested to use the drivers that certified by Microsoft or released by official, especially the drive for graphic card.

3) Scan the computer for viruses or spyware
When the computer is infected by viruses or spyware, lots of system resources will be taken when running. So please use a reliable anti-virus/ spyware program to thoroughly scan your computer and also remember to regularly update your anti-virus program to ensure the latest virus database.

4) Disable some unnecessary startup entries
If too many programs run at the same time, the computer will become slower. So please go to Start -> run -> type “msconfig” to access “Startup”, and then disable some unneeded startup entries to increase computer speed.

5) To increase your computer speed, please go to Start -> Control -> Management Tools -> Services -> right click “RISING REALTIME MONITOR SERVICE” to change it to “Manual”.

6) Check “svchost” process
Svchost.exe is a core process for Windows XP, which also exists in system with NT kernel. In Windows 2000, the number of the svchost.exe is two, and it will be four or more in Windows XP.

7) Check the network connection, especially the network card.
If the XP computer is used to be a server, when receiving request for connection on port 445, it will allocate memory and some amount of CPU resources to provide services for these connections. If overloading, the CPU occupancy rate may become too high. So you have to determine proper settings for “MaxWorkItems” to improve system responsiveness which will be greatly affected ff the value is set incorrectly, or too many system resources is occupied exclusively by a user.
To fix this problem, please open Registry Editor and then locate the branch:
HKEY_LOCAL_MACHINESYSTEM/CurrentControlSet/Services/lanmanserver and then create a new DWORD value named “maxworkitems” in the right window. And then please double click it to enter the below value:
If the computer has more than 512 MB memories, type “1024″; type “256″ if it is less than 512MB.

With the method above, you can easily fix the CPU high occupancy rate. But if you find that you are using a slower computer even though with the above methods, please remember to timely turn off programs that do not need currently to free up more available memory. Besides, I suggest you to periodically defragment your computer to make sure that all files are put in order and coherently.

In a word, it is very easy for us to increase computer speed when the CPU occupancy rate stays at 100%. But please remember not to belittle some tiny points in increasing computer speed.
