jelly, do you have an spare GPU? or another PC to test it with? does the monitor displays any message? what happens if you turn it on without the DVI cable connected?

I had that problem ... everytime i switched ON my pc my monitor would go to power saving mode... I replaced PSU and my sys has worked fine ever since...
But you are correct if CPU is working and monitor is not it is the problem of GPU or monitor
