Sorting Hardware/Software/ Configuration Problems
« on: April 03, 2013, 01:24:43 PM »
One of the first steps in troubleshooting a computer problem (or any other
programmable system problem) is to determine whether the problem is due
to a hardware failure or to faulty software. In most PCs, you can use a significant
event that occurs during the startup process as a key to separate
hardware problems from software problems: the single beep that most PCs
produce between the end of the power-on self test (POST) and the beginning
of the startup process.
Errors that occur, or are displayed, before this beep indicate that a hardware
problem of some type exists. Up to this point in the operation of the system,
only the BIOS and the basic system hardware have been active. The operating
system side of the system does not come into play until after the beep
occurs.
