New Graphics card wont install.

Just got a new graphics card. It wont appear on device manager atall. Fan on the gpu is running fine.

I thouhg its the pcie slot is dead. But i plugged a really old graphics card into the slot and the fan works on that and that is powered by the pcie slot. So it must be working?

does the gfx card actually work?

Make sure you uninstall the old graphics card drivers before installing the new one. Turn off computer, install new card, install new drivers, reboot, should work.

the old graphics card deosnt detect still, but the fan does run off of the pci-e port....

and i have removed the old graphics card drivers, now on the intergrated video atm

helo? lol

tried with two then tried with just the one. when i try install the drivers it says no driver available for my hardware, (it cant find the card) its trying to install those drivers for the onboard video

Update:

Things that may be the issue.

Just updated my BIOS.
Just installed a new psu. from a stock 300W to antec sg 850W
old Gfx card blew 2 capacitors, could this have damaged it?

Any ideas?

tanks for the link. tried all that and no installation. I think the pcie ports just gone. How can i check if its nackered?
