System specs, AMD1200, 512Mb RAM, MSI nvidia GeForce FX5600, 12x DVD, Creative Audigy 1, Window XP Home. I have a problem with my NVIDIA Graphics card (GeForce FX5600 128MB AGP). I use the TV out lead to watch my DVDs with and every so often the TV screen flicks very quickly to show my desktop and then back to the film. I upgraded to this card because Creative didn’t support my DXR3 decoder in windows XP . After a quick chat in the forum on the MSI Web page I got the impression that the card would be better off running on its own IRQ. I had a look at my IRQ settings and all my PCI devices and my AGP card run through IRQ11. The simple thing would be to change the IRQ of my graphics card but with windows XP that aint so simple. All the options to change the settings in Device Manager are greyed out. I read somewhere in NTFS.org that to change it you must change the ACPI computer to Standard Computer in device manager. I did this and after all hell broke loose re-installing devices, only my Graphics card and my firewire card that came with Creative Audigy were on the same IRQ. This created a new problem, when I shut the computer down I got the “It is safe to turn off your pc” screen, which I never had before. Again I looked this up in NTFS and I found that this could be resolved in device manager - hidden devices. I ‘should see the NT ATM / Legacy Interface mode with a red cross on it. Double click it and on the screen that appears at the bottom choose enable from the drop down menu.’ But I didn’t see the NT/ATM/Legacy thingy. I re-installed ACPI and I could switch off my computer but all my PCI devices were on IRQ 11 again. . … …. HELP! If you can make any sense of that, you must know the answer!!!
