    I started having trouble with my Dell 9400 yesterday. It started with a blue screen NMI Parity error message. When I reset the computer I started to get a bunch of vertical green lines made up of dots on the screen during boot up. When windows was loading I got the XP splash screen then everything went black but the HD was still running. I was able to reset into safe mode and load just a VGA driver and everything returned to normal. I tried reinstalling the Nforce drivers from the Dell website and I ended up with the same problem of the screen going black when I was loading windows. I had previously flashed the video card to the 7900GSX. I reflashed it back to the original video BIOS and reflashed the computers bios, but still no luck. I'm running in VGA mode right now, but as soon as I try bumping up the color depth or resolution the screen goes black again. Any ideas??

    Thanks.
