Once all the components and parts have
been installed in the case, it is time to complete the PC assembly
process. First, check the cable connectors. Check to make sure that
all of the pin-1 indicators on the cables match up with all of the
pin-1 indicators on the sockets. Next, make sure all of the
connections are snug. If a connection does not look correct, push on
it gently to seat it. Do not force any connection because the pins and
circuit boards bend and break easily. No connection should be too
difficult to attach. If it is, there is probably something wrong.
After all the cables are secure, check to make sure that all of the
screws are properly tightened. These screws should be secure, but not
overly tight. Finally, when securing the case, make sure no cables or
wires are sticking out or are caught between the parts of the case.
All of the extras such as the sound card, modem card, and so on, can be installed later in the system after the initial boot-up. This ensures the basic computer is working properly before adding new hardware. Take some extra time to double-check all work before turning on the power for the first time. The figure is a post-assembly checklist that should be used before closing the case. Close the newly assembled computer before testing it. This avoids accidental contact with the internal parts while the machine is running, since there is no grounding at this point. This can be hazardous for both the installer and the computer as discussed earlier in this chapter. |
