graphics card problem

[marsden_phil]

i have an nvidia geforce fx 5600 graphics card and ever since i
reinstalled windows i've been having trouble with the driver. i've
downloaded the driver from the website and it installs ok (apart from
saying that its not digitally signed), but whenh i reboot the pc the
driver clearly isn't working as the screen is jerky and an error
appears in device manager. any ideas what i could do?

Have you loaded the appropriate motherboard drivers also?

Since you are using a nVidia based video card, you need to note that the
drivers get updated regularly and several version are WHQL certified. Head
over to www.guru3d.com and look thru the web forums.
