Radeon X1300 card displays blank screen at logon

Have you turned off any onboard video card that is running??

if not go into the bios(f10 when you see the startup screen) and go to video:agp

If this is not the case try a older or newer version of the driver. Start windows in safe mode and install it that way.

remember that you can always start windows in safe mode even if your graphics card is not working as it will run in software mode instead.

You may need to reset your screen to the new card - or it could be a faulty graphics card.

Uninstall your graphics driver first and run driver cleaner in safe mode.
turn off your pc and
reseat your ATI x1300 and spot some dust on its gold interface to clean it. and reinstall gfx card ..
see if it helps

Try removing the new card, booting into BIOS, change your video setting the slot of your card: I believe your card is PCI-E, save changes and exit. When it starts to reboot, turn the computer off, install the new card and then try rebooting again. You may also have to boot into Safe Mode\Uninstall the original video driver or disable that video component and then try rebooting your system.

As far as I am aware, you can not run an ATI card in the same system as an Nvidia card due to driver conflicts.

You must uninstall your previous video card drivers before installing the new card, especially if they were nVidia drivers.

Use PC wizard (search and download) this will detect all drivers needed on your computer note name and number for your video card type into search engine IE ati x300 drivers for your operating system xp vista you should be able to download correct drivers
if does not work for you please leave reply what happens

Check the fan on your video card if it has one. If it does have one and it's not working correctly then it will overheat very quickly.
This sort of issue can be caused by a million things but your description points to the card overheating or the memory on the video card dying.

do the BIOS update !

in the advanced BIOS features there should be a onboard GPU tab, put it on disabled or on initiate AGP/PCI first (depends on the BIOS), so to be sure that the onboard card is disabled !

Connect the display to the HIS ...video card , and at least on bootup there should be info displayed on the screen . If not than : - try to reinsert the video card (bad connection ) (also check if its a card that needs external power source ( i doubt it))
- check if the video card is compatible with the motherboard (should be in the user manual, or on the producers site ... )
- check on another comp. if the card is good ....

hope it helps u ... if not, give more details ....

It could be related to the display resolution settings. If you can boot into "VGA mode", that should get you started.
