ASUS M2N SLI Problem

[Zdn6403]

Hello, I got a Rig with a AMD X2 5600+, 3Gigs of DDR2 ram,750 PSU and I just bought two 9800 GTX 1Gigs. I am trying to set up SLI but I keep getting a black screen and only the mouse cursor is displayed. I tried upgraded with BIOS, uninstalled and reinstalled the display drivers with nvidia's WHQL drivers, even used a different SLI Link and I still get the same issue.

Setting the SLI config in the BIOS to Auto or Dual Video Cards yields the same results, Single Video Card option works without a problem.

Any Ideas?

Does you MB ave a switch between the PCI-E slots to enable SLI? From your post I`d say no, but you`ve not given us the MB name and numbers.
Whose PSU? 750W should be enough but if it`s a cheap one maybe not.

It's a ASUS M2N-SLI. The SLI enable feature is done from within the BIOS. The PSU is a BFG 750W.
