MSI N8400GS-D1GD3H/LP

okay you have to press f8 and boot into safe mode with networking, once you boot into desktop go to control panel and uinstall your old video drivers, restart normally and install drivers for your nvidia card

Thanks, I'll give it a try and let you guys know what happens.

ok, I uninstalled my old video card drivers in device manager, shut down, installed new card, and same results. Splash screen and thats it.

When we swapped it in another computer, we didnt uninstall the previous drivers and it worked.

I'm open to any other suggestions, please.

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

Ok, so I went bare bones on my system to find where the hardware conflict was, only running CPU, one stick of ram and video card. Still doesnt boot past the bios flash screen. For all that have a MSI 975X Platinum Power up edition MB, the MSI N8400GS-D1GD3H/LP VGA card is not compatable.
