cant install graphics card driver

[tiko]

Ok, heres the thing,

 

i just recieved my 7800gt that im getting for christmas, but before storing it away until that special day , i thought i should try it just to see if it works,

 

now i currently have a ati sapphire 300se, so whilst with the x300 still in i uninstalled the ati drivers, then i shut down and stuck in the 7800gt card, then i installed the latest nvidia drivers, and the card worked, so now i had to store it away and then put the x300 back in, so while with the 7800 still in i uninstalled the nvidia drivers, shut down and then stuck the x300 back in, and then installed the drivers,

 

and the drivers install, but after the restart the screen is still 800x600, and when you drag box's across tye screen it lags, which from my experience means that the driver hasn't been installed, as the screen always lags until after i restart where it also fixes the screen to 1280x1024,

 

so the driver obviously isn't installing, ive tried it many times and i have also tried older drivers with no luck, what have i done wrong?

 

also this is what i get in devices, (attachment) no display tab and the x300 is classed as unknown,

 

i have also tried driver cleaner pro, to uninstall the drivers and reinstall

No didn't work just tried it :confused:

vid cards can be tricky sometimes....you pic shows the x300 as ok in the secondary, can you go into your display settings and see if you can use you secondary as your primary.

have you tried right clicking on the yellow question mark and update drivers?

have you tried right clicking on the yellow question mark and update drivers?

 

yes i tried that, but the computer won't pick up on the driver file, i browse and go to the place where the driver is, but it wont show it

Try running driver cleaner, then reinstalling drivers on boot. Idealy Windows should not even need your ATI drivers after putting card back in, they SHOULD still be in cab files. Try blowing out all drivers, then letting it reboot. Then reinstall drivers if you have to.
