No Video After System Power Up

Memory Errors

007-6471-001
If the system powers up and appears to be booting normally but no video is present, try the
following basic solutions:
• Confirm your monitor is plugged in and switched on.
• Check all video cables and ensure they are properly connected.
• If using an optional PCIe video card check the back of the card for LED activity or a fault
indicator. Try opening the system, reseating the PCI card, and rebooting.
If you cannot get a video signal after trying basic solutions contact your support provider.
If your system experiences memory related errors, try these basic troubleshooting steps to resolve
or better identify the problem:
• Confirm that the power supply LED is not indicating an error.
• Shut the system down, remove the covers over the serverboard and make sure that all the
DIMM modules are properly and fully installed.
• You should be using registered ECC DDR4 memory. Also, it is recommended that you use
the same memory type and speed for all DIMMs in the system.
• Check for bad DIMM modules or slots by swapping modules between slots and noting the
results.
Contact your administrator or support provider if the memory errors continue.
