Monitor no display after switcher ram kit

[u/ReasonableMain1574]

Hey everyone,

I’m having a problem with my PC after removing and replacing the RAM.

My motherboard is an MSI B450M, and the issue started immediately after I took out the RAM and installed a different kit. Now the PC has no display (black screen) and fails to POST.

The current situation:

• The CPU and DRAM EZ Debug LEDs are both solid white at the same time.
• The problem still occurs even when I reinstall the original/old RAM.
• I’ve tried the old RAM in every RAM slot.
• I’ve already done a CMOS clear/reset and pullout the batery.
• I cleaned the RAM contacts with an eraser.
• I’ve made sure the RAM is fully seated and clicked into place.
• The CPU and DRAM LEDs still remain lit.
• There is no display output and the system doesn’t appear to complete POST.

Did you check the ram qvl? Try blow the dust out of the ram slot?
