I had a problem come up this morning after trying to burn a CD to take to work with me.Half way through the write process, Roxio encountered an error and had to shut down. I tried to restart Win XP to try it again, but the shutdown process had taken 5 minutes or more, and I had to get on my way. I came home tonight and the screen was black, the light on the monitor was green, and the computer was running normally. I moved the mouse, thinking it had gone into hibernate. Nothing...I restarted a couple of times and even cold booted, but each time it would get past the Win XP splash screen, it would go black and do nothing. I even went as far as clicking all around the screen, hoping I'd hit my user name, and put in the password. I hit the right spot, because after I typed my password and hit enter, I got the Windows welcome sound, but still no video display.I finally reverted to safe mode, so that I could look on the internet to see what might be the problem. I finally had to go in and manually delete the driver files which began with "ati" (I know, bad idea, but NONE of the uninstallers would work in safe mode). Upon the next boot, I got my login screen back, and could move on with no graphics acceleration.I used the uninstallers to get rid of anything ATI and then restarted and reinstalled from the disk that was packaged with the card. Somehow, in this whole process, I removed (a) driver(s) for my AC97 onboard sound and an Ethernet controller. Upon restarting after the reinstall of the Catylist drivers, the Control Center gave me a message about not being able to find any ATI devices installed. I checked the hardware manager, and sure enough, the X850 device had a big yellow "!".I opened the device properties, and there was a message stating that "This device cannot start (Code 10)". Of course the Windows troubleshooter was no help, and I can't find any solutions (other than changing the IRQ of the video card, but right now the card is the only one using IRQ 19). So, I ask this community whether there is anything that I can do, short of formatting the HD and starting over.Thanks in advance

More info on your system please.In the meantime, try reinstalling DirectX, then reboot, and then reinstall your motherboard's chipset drivers, then reboot again. You'll have to follow up this routine with reinstalling the video drivers. Your chipset drivers have definately been hosed.On a side note, I finally gave up on Roxio's stuff last week.. In doing so I found alost 4000 leftover registry entries for their stuff. 4000! Very ugly. I'm now using Fireman 2.0, and while the GUI isn't as pretty as Roxio's I'm quite happy with it. Seems faster, too.Good luck,Greg

Thanks for the tips. I'm currently running a Gigabyte GA-7NNXP with a Athlon XP3200 and a Radeon X850 Pro and a gig of RAM. The mobo is of the Nvidia NForce 4 chipset, and does support 8X AGP. I've tried the drivers for both the motherboard and the video card that were supplied on disc and that I've downloaded off the manufacturer's websites. The motherboard is flashed to the F20 (latest) bios.I have re-installed the chipset drivers, but not DX, I'll give that a try now.EDIT: Tried reinstalling DX, followed by the chipset drivers, followed by the video drivers...no luck.

If you have video at boot-up (POST) and in safe mode then your card is healthy. Use Drivercleaner Pro to rid the system of the existing ATI stuff. Follow the Readme to the letter and it will cleanse your registry. Also, before rebooting back into Windws you should manually delete all ATI driver set-up files. Then install the video drivers again.Greg
