70. Potential Problems
Say you have a 2 GHz Pentium 4 that is designed to be run on a 133 MHz bus, but it is only being run at 100 MHz. The clock speed of the processor is determined by multiplying the FSB by the multiplier (each processor has a multiplier that cannot be changed and determines the speed of the chip)500 MHz is a pretty significant loss of crunching power and you do not want to make that mistake.
Overclocking is running the FSB higher than what the processor is engineered to run at. If you have a processor that is designed to run at 133 MHz and you have the FSB set anything above that, the processor will be overclocked. Generally overclocking by modest amounts is safe provided that you have good cooling.
Disclaimer: Overclocking will void your warranties and can damage your processor if the proper precautions are not taken.

There are many potential causes for this, but the more common are:
• All components not seated properly. Check to make sure that everything you've installed is seated completely. RAM sticks need to be firmly pressed into position, so that the plastic locks pop up to secure them. Audio/Video cards need to be securely seated in their slots. Check all cables, connectors and plugs.
• Power switch actually connected to motherboard? Don't laugh ... The buttons and LED's on the front of the case do not magically work, there are connections that must be made to the proper receptacles on the motherboard.
To determine the proper way to connect the wires, follow the instructions in the motherboard manual. Check and double-check to make sure that the connections are plugged into the proper places. Some reasons for the buttons and/or LED's not functioning properly included reversed polarity and making the connections to the wrong plugs. There have been numerous incidents where someone wasn't sure how to connect the wire leads from the case to the motherboard - or what their purpose was.
The case power leads can be seen in the graphic above.
