High CPU Usage
A collection of useful resources for determining and dealing with the source of 100% CPU usage problems, which cause the system to become unresponsive either intermittently or continuously.
Note that the System Idle Process is supposed to have a high CPU usage rate at idle. This process accounts for unused system time. If your system is responsive and the System Idle Process CPU usage is high, then you do not have a CPU usage issue.

Introduction
 | If the knowledgebase articles below don't help you to resolve your high or 100 percent CPU usage issue, bear in mind that corrupt system files and drivers, out of date drivers, corrupt applications, viruses, trojans, worms and insufficient RAM can all cause CPU usage to go high. Use the resources that appear after the Knowledgebase Articles for further help in locating the source of the problem:  | ||
 | Software Modems (Internal PCI Modems) If you are experiencing high CPU usage when you connect to the internet and at various other times whilst connected and if you have an internal modem, then the high CPU usage may be normal behaviour. Software modems typically have much less hardware than a hardware modem, which is why they cost much less than normal modems. Because the software modem has fewer components, it must draw on the CPU in order to operate. Some software modems will have more impact on the CPU than others. CPU load can range from light to moderate, to decreasing the performance of the computer completely. If this is your situation, there isn't much you can do, short of buying an external modem. |
