Is AGP 2.0/x4 compatible with AGP 3.0/x4?

uh I ordered a Radeon Ati 9800 Pro it worked fine with the drivers that came with my Windows XP SP2 then i used my standard 5.4 catalyist Drivers then my screen went all fuzzy. Then i booted into Safe Mode used Driver cleaner nuked the archieve installed catalyists again but that didn't work either
I used Ohm's law to determine the watts on my fan 3.9Amps x 120 Volts = aprox 450 Watts which i think is satisfactory

So i tried Omega Drivers same results Then i checked the label on Minimal Requirements for my Video Card & it said AGP 3.0 4x/8x compatible slot i had AGP 2.0 4x one my Vaio Manufactor pointed that out i think. Now i need someone to please comfirm my theory why they won't work correctly.

Now

 

NVM i just realized AGP 2.0 is compatible with x1, x2,x4 and that AGP 3.0 supports x1, x2, x4, x8 since my AGP card is a Radeon 9800 pro it's therefore compatible with AGP 2.0 1.5v 4x =). I'm going to rewire my computers onboard power sources for the card to see if that will do it.
