I just connected my computer, but there's no sign of life! I've ensured that the power is connected to the motherboard and the CPU. What could I be missing?

It could be something as simple as the power switch on your power supply not being flipped on. Double-check that first since it’s a common oversight. Also, ensure that all your connections are secure.

Sounds like you might have missed flipping the power switch on the PSU! I once did that too and it had me scratching my head for a while. If the fans are spinning but the DRAM light is red, that could point to a RAM issue. Try reseating the RAM sticks and see if that helps.

Have you checked if the power switch on your case is turned on? I know that can be easy to overlook when you're setting things up.
