blank screen after Geforce 7800gs install

I've installed a new card: pov GeFroce 7800GS 256Mb AGP
My PC (Dim 4600) is dual boot XP/Ubuntu when I boot up the screen is blank. I get no BIOS message and no grub menu.
Ubuntu is my default OS and its login screen appears once booting is finished, I can then use it as normal.
If I change XP to be the default the screen just stays blank and I never see the windows login.

I've flashed the BIOS from A07 to A12, I've got 350Watt PSU.

Does anyone know whats happening or what I can do?

If linux works does that mean that the card itself is not faulty?

    Sounds like a software conflict. What card did you have before ? Have you ever had Rivatuner installed ?

    My old card was an nVidia GeForce 440 MMX which came with the PC. I removed the old drivers before installing the new card, and for the heck I tried it all again without removing the drivers.
    I've never had Rivatuner installed.

    If you haven't done so, download Drivercleaner and make sure you follow the directions on how to use in the readme. Then install the 91.33 drivers and see if that works.
     
    I usually recommend to people to reinstall Windows after upgrading Video cards. I always do. There is just to much that can happen with old files remaining from the old video card in different places.
     
    The PSU should not be an issue as long as you have the 7800 plugged into it.
     
    I've never done a dual boot before, so I don't know weather that could be causing a problem or not.

    Thanks for the suggestions, I've heard other people mention DriverCleaner, I'll give that a shot.

    I tried DriverCleaner with no joy. Guess I'll try a windows reinstall, not sure how that's going to work.

    I think it's the dual boot functionality that is causing internal conflicts. I am not familiar with dual booting, and the relative success rates with adding new AGP cards to dual-boot PCs, but the steps you have taken are correct. But did you plug the 7800 GS into the PSU via the spare molex cable running off the Hard Drive power dongle?

    jdwssll: my card is the one linked to by thatsme

    Cypherus: I have the card connected to it's own cable, not one that is split and shared with a drive.

    I tried taking out all the PCI cards in case there was some weird conflict.

    I notice the power requirements for the BGF are 400Watts while for the POV it's 350Watts. I assume these are essentially the same card. I should be able to get my hands on a bigger PSU easily enough to give it a try.
