Its a bit complicated but i think the short answer is No.
I beleive your board has onboard graphics one of the ATI Radeon HD 4200 series i think, i could check but the exact one isnt really an issue. The point is the Nvidia Drivers will disable the PhysX support if it detects ATI graphics hardware and so your stuffed.
If you disable the onboard in the bios its still there so i dont think that will work either unfortunatly.
I have read that a AMD board with no onboard "should" do it but thats of no help to you is it.
So as far as i know, sorry but No.
Wait for some more responses as others may know more .
