I just finished upgrading My GPU, CPU and PSU and now my display doesn't work, the monitor seems to work just fine (it gives "NO SIGNAL") yet no image.
I also noticed that the mouse gives off no light and the keyboard caps lock doesn't seem to work, also long pressing the power button doesn't turn off the pc, I have no idea if the problems are related.
So far I've tried using different cables, removing and putting back in the GPU and unplugging and re plugging everything I could find.
If anyone has any help I'll appreciate it.
