Getting no video or beep sounds.

[Ducksworth]

So, I've been having this problem for a good while. When I turn on my computer, I get no beeps and monitor does not turn on. I recently thought it was the MB, returned it and got it fixed. Still does it. Took out my ram, no beeps at all. Tried my psu. Hooked it up to another computer, works fine. Seen countless posts, so I think the only thing is the cpu now? Or perhaps a harddrive. Any help would be appreciated. It's been over a week now.
Also, my apologies if this isn't in the right place. Feel free to guide me to the correct place.
