If you replace the processor, make sure the new processor is installed correctly, and that the notch on the processor is aligned correctly on the system board. If you did not align it correctly, the system won't start. Also make sure the jumpers are set correctly for your processor. For more information, see "Installing Memory Modules (SIMMs)," "Upgrading the Processor," and "Changing the Jumper Settings" in Chapter 4. You may have installed option cards or drives that exceed the system's power limits. Check the power limits listed under "Option Slot Power Limits" in Appendix A. The Computer Does Not Respond The computer locks up. Wait a few moments; if your computer does not respond after a reasonable length of time, press Ctrl Alt Del and follow the instructions on the screen. If that doesn't work, press the RESET button. Note If you press Ctrl Alt Del or RESET, you will lose any data you did not save. You may have installed memory using SIMMs that work at the wrong speed. Install the correct SIMMs. (See "Installing Memory Modules [SIMMs]," in Chapter 4.) Your system may have overheated. If you upgraded the processor yourself, make sure you have an adequate heat sink installed. Traubleshooting 7-5
