No Image, Help!

[The Notorious SMALL]

So I set my computer up, which I have not had access to for two weeks and turned it on, first of I was treated to inconsistent speeds from my graphics cards fan, as if it was turning off and on really quickly. Next there was no picture on my monitor. So I took out my graphics card and tried the integrated graphics and I still got nothing from the monitor. I tried a different monitor, still didn't work. I bought some canned air cleaned everything really thoroughly and I still get no picture and my graphics card still makes the noise.

So what else can I try, I'm just really hoping it isn't my motherboard.


Specs:
Phenom II X4 920
HIS 4870
Foxconn 790gx
Seagate 160gb HDD
Corsair Dominator DDR2 (2x2gb)
Corsair 650 Watt PSU
Artic cooler 64

I think i've had this problem before, it turned out to be the psu was turning itself on and off confusing the hell out of the mobo/cpu/gpu and causing all the fans to do exactly that. If you have a spare psu, try testing it on the rest of the system to see if it fixes the problem

Its only the GPU's fan, all the others work fine.
