You have finally gotten the last component in the mail, and you are ready to start assembling everything. It goes together easily, and you press the power button for the first time. Nothing happens. Maybe the fans spin up briefly, but they turn right back off. What do you do now? I have compiled a small list of the most common custom computer problems that we see at Reboot Computers.

Various Power Supply Issues

Power supply issues are probably the most common source of issues with a new build. To sum it up, we see a few things happen here:

1. Not plugging in all of the power cables required for the computer to operate. Ensure that the motherboard’s 20+4 pin connector, CPU power connector, and PCIe power connectors are actually connected.
2. Not completely plugging in required power cables. Oftentimes the connectors all appear to be plugged in, but aren’t. Ensure that there is no gap between the power connector and its receiving end on the component. These can sometimes require more force than you would think reasonable.
3. Power supplies are typically switched to the “off” position when they are new. Check the physical switch on the back of the unit.
4. Modular cables plugged in incorrectly. Careful for this one. Remove your modular cables and check to be sure that the keys (plastic shaped to dictate how the cable should be attached) line up correctly. Unfortunately, if this is your issue you may have damaged some components.

Incorrectly Installed CPU Cooler

Another common fault that we experience is an incorrectly installed CPU heatsink. Reexamine the instructions for installing your heatsink, paying close attention to the pieces required for your CPU socket. Using the incorrect pieces here can cause a small gap between your heatsink and CPU, cooking your processor in seconds. If you find that this is your issue, you will likely need a new CPU. A properly affixed heatsink needs to sit firmly on the CPU to dissipate its heat.

Badly Seated Components

Similar to one of the  popular power supply issues, many will neglect to use sufficient force to install their RAM or graphics card. Try removing your RAM and graphics card, and reinstalling them. Both components require an excellent connection for the computer to boot and operate correctly. While you’re at it, try removing the CMOS battery for a minute, and reinstalling it.
