I think there's been a mis-understanding of where exactly the system is hanging up. It's hanging up at the bios flash screen (the spaceship graphic) not allowing even enter bios.
I tried booting with a start-up disk, same result. t's not alowing the system to even get to start windows, so it can't be a regestry issue. I'm pretty sure it's a hardware conflict but it doesn't make sence that 2 products by the same company aren't compatible.
Also, my current card is and MSI nvidia as well, its a NX7100-256
