Pci-e graphics card not working

[Flashhead2010]

Purchased a PCI-E graphics card to replace my onboard graphics card, now there is no boot up even to the BIOS,
If i unplug the card and go back to the original onboard grapics it is still fine,
I can't see any way to disable the onboard graphics in BIOS and there are no jumper links, so i assume it must be automatic.
Any suggestions? It was ATI xpress 200 graphics and the new card is a nvideo 7000 series.

Reinstall your windows some time the problem with your windows

There is an option in the BIOS menu, under integrated something (depends on the mobo).

If you cannot find the option, then your PCI-E card is not properly seated in the slot. What mobo do you have?
