After you have installed a processor, what should you do if you turn on the system and power comes on but you don't see any output on the screen and the system does not seem to be going through its normal boot procedure?

What will be an ideal response?

If the power comes on (you hear the fan spinning and see lights), but the system fails to work, most likely the processor is not seated solidly in the socket or some power cord has not yet been connected or is not solidly connected. Turn everything off, unplug the power cord, press the power button to drain power, open the case, and recheck your installation.
