- no video after move to new case.

[BishopTango]

Hi, I needed to move my system to a new case to accommodate a larger video card.  I didn't remove the cpu or RAM from the board, but gently removed it from the existing HP case and reinstalled in the new case.

I have also upgraded the PSU.  Upon powerup, the lights on the case fans and the video card come on, all fans spin up, but no video of any kind.  I've tried multiple cards, and confirmed those same cards work fine in other systems, but I get no splash screen or video of any kind at any time.

Any suggestions?

Hello, if I understand you just have replace your case, PSU and video card?? And your PC has any video signal, even with the original video card?? Do you have tried to reinstall your original power supply?? 

And if you can try to remove your graphic card and connect your screen directly to your motherboard.

Hi

It is also a good idea to disable Secure boot and enable Legacy support (Link) and uninstall the current graphics card driver before installing the new graphics card.
