help - problems with new gfx card

[stu_]

have just installed new nvidia 7600gt agp card

i have 400w psu
1024mb ram
amd athlon 64 3000+ cpu

pc now runs VERY VERY slowly with every desktop icon taking time to draw individually and screen switching off and on every so often and hanging frequently

can't use menus and it doesn't seem to be able to open more than 2 windows at a time

can't access control panel to check settings etc.

any ideas please?

uninstall and then reinstall the graphics card drivers and get the new ones from nvidia.

did you install new nvidia drivers? sounds like the card hasnt been installed properly. happens when i install a new card, if i scroll on the internet it draws 1 line at a time.

installed drivers that came with card

problem now is that i can't get into control panel to uninstall current drivers

will i be ok just pulling the card?

not while its running no... how can you not get into control panel? try and log on as administrator and uninstall them. or just download the ones from nvidia and install them. they should overwrite the old ones.

Whats your PSU like ? Whose the manufacturer, whats the combined 12v rails etc ?

have tried all ways with drivers and no response - screen runs so slowly that i can't use pc at all and have to reinstall old card each time i want to re-set or access internet etc.

it runs too slowly to open any menus

have decided to go for an upgraded psu

i will go for 500w as others have told me their 7600gt runs ok with this size but is there anything i should look out for when selecting one. i.e. are there different types or will any psu do?

Can you boot into safe mode and see if you can sort out the problem from there?

[Metier9]

check the refresh rate as well, the XXHz

update........

replaced psu
updated BIOS to latest version
switched BIOS to enable AGP recognition of nvidia card - 'deep FIFO' or something!
used latest nvidia drivers

uninstalled and reinstalled and eventually it worked!

thanks to all who replied for their support
