New PC doesn’t appear to be booting

[Jammy_D]

I’ve just finished building a “new” PC (swapped out Mobo, RAM, and CPU). When it’s turned on, my case fans/lights turn on, the GPU, CPU and PSU fans spin, and the hard drive spins up. It’s plugged from the integrated graphics to a monitor that was working with my last PC.
However, nothing comes on screen. My keyboard lights up but my monitor says there’s no signal.

The HDD activity LED also doesn’t do anything, I’ve tried it plugged in both ways. I’ve also tried clearing CMOS.

I also don’t have a case speaker, so no POST beeps
Specs:
GTX1050ti
i3-8100
ASUS H310M-K (stock cooler)
1x8 HyperX RAM

I’ve gone through the normal checklist, and nothing seems to fix it.

are you plugging in the monitor to GPU or MB? a new install of windows will be needed as well you shouldn't just plug in the old drive with windows on it and try to run it that way, it doesn't work well and causes issues. if your GPU is plugged into the motherboard, your monitor needs to connect to GPU

I’m booting without a GPU or hard drive, I’m just trying to get to BIOS. The cable is connected to mobo graphics

Problem solved, RAM was not seated correctly.
