So in trying to understand as to be able to help...
You had to replace the power supply, right? Was the amber light present prior to you taking this step? What led you to feel you had to replace the power supply?
At the same time as replacing the power supply, you also bought a new nVIDIA GPU, correct? What make / model card did you get?
You swapped out both and now you get nothing, right? You tried to test the power supply using the paper clip method, but nothing happens?
Are there any post-code beeps? When you push the power switch on, are there any other symptoms besides just the solid amber light on the motherboard? Where on the motherboard does the light come on? Is there any indicator near the light that may give an idea as to what the issue is? Any way you can upload a picture here?
