Thank you for writing to Dell Community Forum.
Please check with one new hardware at a time and check if the system is booting normally.
Can you check in BIOS <F2> if they are listed.
Please private message us the service tag of the system along with your email id
I have booted with each one individually installed, as well as without either piece of hardware, and I am still in the loop. The SSD shows up in BIOS, but I'm not sure where I would find the RAM in the BIOS. My service tag is CLGJ8B2.
Oops, just realized I accidentally created a duplicate thread.
Anyways, I should have specified; I installed another 8GB RAM alongside the original 8GB RAM. I have tried booting with only the original RAM, and the same thing happens.
Next question : was the SSD installed with the original drive, or worse - was the original drive cloned to the SSD and then left in place while the system was booted?
Sorry, not quite sure what you mean; my knowledge with hardware isn't very extensive. All I did was install the SSD in to the M.2 slot as well as the RAM in its corresponding slot. The stock drive for the laptop is a 2.5" 1TB HDD/8GB SSD hybrid. The laptop feature an open M.2 slot, which is where I installed the SSD.
Meant to clarify in that post: I did not tamper with the Samsung SSD at all before installing it. It went right from the package in to the computer.
Best approach: Remove the new memory and the SSD and use your factory recovery media to reload the original software image. Then try the upgrades, memory first, one at a time.
