HD 4870 Device Manager issues

[oakley_burn]

Greetings to all once again,

ok here's the problem, i've recently bought a Sapphire HD4870 512MB card that fits into my system beautifully. When i start my machine the device manager recognizes the card but does not start the drivers (windows error code 10). if i then disable the device and then enable it, the drivers work and all is well, although i cannot start ATi CCC. when i try to start ATi CCC it gives me a RUNDLL error with Ntdll.dll as the module. Have checked Ntdll.dll, hal.dll and boot.ini to make sure all is well (they run together apparantly) and no dramas.

i did have a NVidia 6600XT that ran with no issues whatsoever.

my system,

AMD Athon 64 X2 6000+ 3.01 Ghz
2 Ghz DDR2 RAM @ 800mhz
windows XP 64 bit professional edition with service pack 2

i've done all the usual things like uninstall and reinstall with latest and roll back drivers to see if this clears the problem - no effect.

used windows update to make sure there are no windows problems - all clear.

it seems weird that the device works perfectly, i just have to manually enable the drivers.

any ideas?:confused::confused:

Download CCleaner (crap cleaner) and driversweeper. Run Driversweeper in safe mode to remove any excess nvidia video drivers then reboot and run ccleaner to clean out the registry.

I'm pretty sure this should do it for you.

If not then what's the rest of your setup? Motherboard, PSU, etc..


edit: oh, xp64... *cringe* I hope this helps you out man...

hiya, ran both programs, still no change.

psu - 750W
m/b gigabyte ga-ma74gm-s2h

i originally had xp pro on the machine then got recommended for xp64 as it would optimize my system better.

maybe thinking its a windows thing not a ati driver problem.

This might sound stupid, but did you make sure you got the xp64 catalyst drivers?

If you did then I'm going to go ahead and say that it's your OS. XP64 has horribly bad driver support since vista came out right after it.
