I bought a new 16GB ram stick, and my computer wont boot. I took out the old ram stick to check if it would boot with the new ram stick but nothing. After, I tried using the old stick again and it didnt work. When I put the stick in I pressed hard but I didnt hear a click. I also checked the notches and slots but I dont know whats wrong. When I try to boot the PC the motherboard lights up, then the graphics card light but then it just stays on the memory light and doesnt boot. Im not very good with PCs so I'd appreciate help. I have x64 bit Windows.
