System Does Not Boot up at First Integration
[1] 2x2 or 2x4 Power Connector Not Plugged In
If the power supply cable with the 2x2 connector or 2x4 connector (depending on your desktop board), is not plugged into the 12V processor core voltage connector located near the processor socket, the system will not boot up. You will see lights onboard and on the chassis front panel and the processor fan will spin, but nothing will appear on the monitor. See figures below for cable placement.

[2] Processor Issues
No boot situations can be caused by any of the following.
If you have installed an incompatible processor, the system will not boot. Ensure the selected processor model is correct for your desktop board. Some processors require specific desktop board versions and BIOS revisions. To find the supported processor list for your board, go to Supported Processors. If the processor is compatible, try removing and reinstalling the processor to ensure it is installed correctly.
If the processor overheats, the system may not boot or may shut down shortly after booting.
• Make sure the fans on the processor are connected properly and running.
• Make sure that the thermal interface material or the thermal grease is applied to the
processor properly.
• Make sure that the power supply fan is running properly and any other external

dimmed where you cannot see anything on the monitor.
dimmed where you cannot see anything on the monitor.
• Most monitors have a light indicating its current status:
- A green light indicates the monitor has sufficient power and is getting a video signal.
- An amber light appears if the monitor has power but it is not getting a video signal
from the computer. This indicates the problem is most likely in the computer.
from the computer. This indicates the problem is most likely in the computer.
- If the light does not turn on at all, it is likely a problem with the monitor itself.
Make sure that the monitor is connected to a working AC outlet. If there is an
on/off switch for the outlet, make sure the switch is on. If the problem still
persists, try replacing the monitor or try the monitor on different AC outlet
or a different system.

[7] Electrical Short or Overload
An electrical short or overload may cause a system not to boot.
Check for shorts and overloads by removing non-essential items such as extra controller cards or IDE/ATAPI devices. Keep only the desktop board, power supply, memory and processor installed. If the system boots, it is possible there is a short or overload with one of the components that you removed or one of those components is faulty. Replace each of non-essential items one at a time until you isolate which one is causing the problem.
If the problem occurs even after removing the non-essential components, the problem has to be with the desktop board, power supply, memory or processor.
