getting blank screen on installing nvidia 250 card

[lyleman222]

hi guys

im getting a blank screen when replacing my nvidia 7900GS 256mb with a nvidia 250 1GB, i have followed a few of the tips ive seen on the net but am getting nowhere, so ive followed the instructions to use integrated card and diable old card etc , im using a asus A8-8VM MB and have thermlake 470W PSU soshould be ok . new card has power and fan is spinning up ok, but nothing
funny when in switch from new card to intergrated on boot up i can see windows is booting , strange, any ideas guys?

in the bios try changing the video dram setting. try setting it to 256 or 512. see if the new card then works. if not check to see if your running an old bios file on your mb.

thanks for reply, will check that - im running the latest BIOS from asus for my MB

page 2-29 of the mb user guild turn off sli support and turn on pci 2.0 supprt.

dont see that in my manual , sorry may have typo'd my MB model its a ASUS A8V-VM

i mean would a new card not work even if there were previous nvidia drivers installed? so in other words nvidia card for nvidia card?

just to confirm im trying to fit a 250 GTS into a pcie 1.1 x16 card slot this should work right as BW comp?

just another point would i get black screen if the NVIDIA drivers were not the correct drivers for the card im adding? anyone have any ideas guys on this question? thanks
