Well, you have gotten this far. Congratulations! You have now completed the hardware portion of putting together your PC.
Admittedly, if you are following this tutorial to the letter, your PC is rather bare-boned at this point. It is highly likely you will be installing some additional hardware such as a network interface card (NIC), a sound card, maybe a dial-up modem or other hardware. Some people like to install everything right away. Usually when I build a PC, I like to start with the basics. The reason is that it makes the installation process of your operating system easier. Once you have your operating system installed, you can then go in and install your additional hardware and get those items working one at a time. It can be a little daunting to try to get everything working at the same time, especially simultaneously to installing the operating system itself.
Now, you are about ready to turn your new PC on for the first time. But before we do so we need to give everything the once over and make sure we didn’t miss something. So, with a flashlight, check all of your work. It is better to “waste” the time than to engage in wasted time trying to track down why the system will not boot.
Review all your connections and installations as completed in prior steps. Here is a bulleted list of highlights to guide you:
- Drives properly connected to the power supply
- CPU fan attached to the power supply or to the power connector on the motherboard
- If this is an older AT machine, ensure the P8 and P9 main power connectors are installed properly, with black wires in middle.
- The 110/220 volt switch on the back of the power supply is configured properly for your area
- Ribbon cables attached correctly and securely. If using rounded cables, the arrow on the connectors indicating Pin 1 should be aligned with Pin 1 on all drive connections. On gray cables, ensure the red edge is aligned with Pin 1.
- All connections tight, no connectors off by one set of pins
- If there are any key motherboard settings which are jumper-controlled, ensure these settings are correct
- No wires or ribbon cables protruding into fan blades
- Power switch connector on ATX machines properly connected to the PWR_SW pins on the motherboard. If this is not properly done, the machine may not even turn on when the switch is pressed.
