Dear Techspot,

I'm at a dead end with my attempts to enable SLI on my system. I've done everything I can. Activating coolbits hasn't worked (I think because the nature of the nvidia software has changed since coolbits was introduced a few years back). My motherboard is definitely set properly as I've followed the instructions in my manual. Here is the latest system report:

Notably the PCI Express section says PCI-E x8 which is odd. My motherboard is an Asus A8N-SLI Deluxe so it should be fine. The other thing is the video bios is very slightly different for each card along with the IRQ

Please help guys. Im really struggling on this.
 
I've just reinstalled my NVIDIA drivers and I got a "Hardware not working properly" message after the system tried to find drivers for the "other PCI Bridge Device". Is this my problem
