1: Unbox your PC
It's easiest to open the top of the box entirely, then carefully tilt it upside down onto a soft surface.
2: Remove Protective Foam
Unscrew the 2 or 4 screws holding on the left side panel and set it aside somewhere safe. Carefully pull out the shipping foam, squeezing if necessary to make it smaller. For Dual GPU workstations, please review our help article.
3: Inspect the cables, and/or make minor adjustments if you wish before re-installing the side panel. If your PC came with WiFi antennas, hand-tighten them to the round gold contacts on the back of your PC.
4: Connect the power cable, and the display cable to the graphics card. Do not use the motherboard's display outputs. Ensure the power supply is in "I" position, not "O". Ensure your monitor is on, and in its settings, input set to Auto, or the correct input port.
5: Press the power button.
Some modern systems may take 1-3 minutes to train memory on first start. Drivers are preinstalled, get gaming in minutes!
If the machine still isn't turning on, please check the following:
Power Supply:
Please ensure the switch near the power cable is in "I" on position, not "O" off position.
Monitor:
Please ensure your monitor is set to the correct input port (HDMI or DisplayPort), and you're using the inputs from the graphics card in the middle of the PC, not the motherboard on top of the PC. If your display has multiple HDMI/DisplayPorts, make sure the correct one is selected, or try another one.
Graphics Card:
It may have shifted out of its motherboard slot in shipping, and/or a power cable came loose.
Please follow these steps:
Shut down, then unplug PC. For most PCs, laying it flat on its right side is easiest.
Remove the side panel, usually held in by 2 screws in back, or 4 on its side.
Ensure the power cables are fully plugged in by firmly pressing them in, then press the graphics card into its slot as well.
In rare cases, the graphics card may need to be reseated. To do so, unscrew the graphics card from the case, usually 1-4 screws on its left. Depress the PCI-E latch on the motherboard, and ensure it's fully down before pulling the graphics card up. You may need a long flat object in a tight configuration if an air cooler is in the way.
Memory:
On the motherboard, the 2 or 4 vertical RAM sticks can sometimes get jolted loose from their slots. Firmly press them in and ensure their latches are fully locked.
Reset Motherboard:
Your case may have a button to reset the motherboard. If not, or if this button is being used for RGB controls, please remove and re-install the CMOS battery after waiting 30 seconds.
Loose Cables:
Please ensure your machine is fully turned off and unplugged before opening. Check for any cables that may have become partially unplugged after shipping.
