I opened my computer to see if I could fit any more RAM sticks in which I could't, there were just two 16GBXL sticks with a red case around them (I took them out). I put them back in and closed it up. About 5 minutes later I turned it on but nothing was showing on screen, I tried changing cables and even swapped from vga to hdmi and it didn't work. It worked before I took the sticks out.

I'm not too good with things like this so I'd like an idiots guide if possible.

The computer is just under a year old and is a custom I bought from Mesh.
Thanks.

I tried that numerous times but nothing seems to happen, does it matter what way they face?
