My Victus 15L i5 12400, 8GB DDR4, fails to start with black screen after swapped a ram and back

My Victus 15L i5 12400, 8GB DDR4, fails to start with black screen after swapped a ram and it still has black screen even after I swapped the stock RAM back! Please help! I can't even enter the BIOS to fix the problem!

Welcome to the HP Forum. Sawadee Khap 🙏 (Hello)!

Some HP PCs have problems with certain retail memory modules. I could see a POST problem if you installed unsupported memory modules.

But it's not good to see your PC will not POST after reinstalling the HP factory memory modules.

You can't get to the BIOS if the PC will not POST.

Memory Module Installation:

Check to see if the HP memory modules are fully seated. Reseat the modules. Double verify the memory modules are fully seated and the memory slot locking tabs are secure.

Try each HP memory module, one at a time, in each memory slot if you have multiple HP memory modules.

Start the PC after each memory module iteration to check for a good POST.

Memory Module or Memory Slot Damage:

It's unusual to damage the memory module's gold pins or the memory slot but it can happen.

Examine the HP memory modules for any damage. Check the memory slots for damage.

MB CR2032 Battery:

You could try removing the CR2032 MB battery to reset the CMOS when the PC is disconnected from AC power.

Let the PC sit for about 5 minutes before reinstalling the CR2032 MB battery.

Final Thoughts:

You may unfortunately have a hardware issue (if the PC will not POST) after doing all of the above steps to resolve the startup problem.

A local PC Tech may have to take a look to determine what has happened.

Thank you so much! I tried all those, and even tried more. I ensured no obvious mistakes were made during each attempt to recover. It is a hard thing to accept, but I'm leaning towards a broken motherboard, maybe a fuse got broken, maybe a capacitor popped. It's just really insane a simple RAM swap caused all this. And I don't think the motherboard is worth it to replace for a premium cost.

Sorry to see the PC will not POST.
