Put your old gpu back, uninstall driver, turnoff, put in new gpu. The gpu should run at vga resolution for you to install a new driver from disk. Then update to newest driver.

Need to know your set up(PSU, Mobo)
Did you plug in the external power cables to your 6870?
On-board graphics?
Which card upgrade from?

You need to disable on board graphics in the bios.

just remember to uninstall nvidia drivers before upgrade and disable on board graphics in bios on power-up after install.

Ok, that is good. At least you have picture. It looks like you have 2 computer, download the newest driver from amd and use a usb to install the latest driver.

You might have to update your mobo bios, you can check with manufactures website!
I know its a little late but you should always research before not after upgrading, to avoid unpleasant surprises.

ok I think its time for system restore to when you still have nvidia driver. then you can put the old card back in and try again in correct sequence.

Well I though that he is not familiar with his hardware, so I am trying to lead him to solve the problem with an alternative approach without the need to flash bios etc.

He may not have to flash it. Its probably in bios settings that hes missing so the next step would be to identify the mobo.

The 6870 might be incompatible with his set-up.
Onboard Nvidia chipset = AMD no work.

I am betting on the backward compatibility of pci-e if it is hardware. May be he is one of those 2.1 and 1.0 incompatible combination. Never heard of the nvidia chipset amd gpu incompatibility before. Did a google search, I think it is rumor.

I think I will leave the problem for you to solve, if ryoere turn up again. It's late in Australia.
