Black screen after installing new set of RAM

[Vampyra]

I bought myself a new set of RAM and installed it, but after turning my PC on again my screens did not turn on.. anyone knows how to solve this?

The motherboard supports max 64GB RAM - 2666 Mhz, i have a set of 2x32GB RAM 2666Mhz. The old set is 2x4GB 2666Mhz. It’s a windows PC.

I have absolutely no clue what to do

Can you post the brand and model name or number of the CPU, the MB and the new RAM.

CPU model: Intel Core i5 10400 @ 2.90GHz | Comet Lake 14nm Technology
MB ? cant find anything whatsoever about MB’s in my specs concerning CPU
New RAM: Crucial Standard DDR4 - 2666 UDIMM 1,2V CL19 2x32GB | CT32G4DFD8266

laptop or desktop?

if desktop, you’ll have to open up the case and the motherboard manufacturer’s name will be written in white.
there will be the make/model and version number as well.
something like Gigabyte H310M SP2 (rev 1.1)

Ah, i’m sorry its:

Gigabyte H410M S2H V2, mATX, 2xDDR4

and it’s a desktop (:

Did you make sure that all of the power and data connections are snug may have one that is loose.

Make sure that you connected the display to the display card.

Do you hear any beeps and or patterns?

If you put back in the original RAM does the system work?

[Bruce]

your new RAM is listed in the Qualified Vendors List, so it should work.

as Rustys has said, put back in the original RAM to confirm it still works.
then put back a new stick, one at a time, and see how that goes.

It turns out one of them is DOA one works in both slots, the other one doesnt work in either slots.. so I’m returning half my product. Thank you all for helping out, it means a lot! (:

Not ideal but at least you have identified the problem and thanks for letting us know (y)

Just a fyi, both sticks should be returned as when you intend to use more than one stick of RAM you should always purchase the RAM in kits, in this instance a dual channel kit, mixing RAM seldom works out trouble free.
