8600gt black flickering screen

[00mpollard]

Hey guys

i have just installed 7 32bit onto a clean hdd, everything is great apart from my 8600gt!

i have an asrock nf6g vsta (built in vga), the built in vga works fine but my 8600gt displays a black flickering screen in vga mode and dvi (it sometimes comes up with a fraction of the top part of the screen but it is flickering)

when i have tried both out (onboard and 8600), i have disabled the other display adaptor so there shouldnt be conflict about them both running at once

i have previously had 7 installed with no problems with this card, but hard drive failiure leaded to a new drive and now this error

my display is a samsung 2232bw too

help would be nice!

thanks guys

Hi 00mpollard.......

have you any means of testing the 8600 elsewhere..??

have you reinstalled GPU drivers in ''safe mode''..??

do you have the correct drivers for your monitor (check device manager)..??

the fact it works with the on board VGA with no issues points towards the card or drivers...
