Computer not detecting graphics card

On my newly built computer, I was having problems with no display when I first turned it on. I tried booting without my graphics card in, and it started up fine. I went to BIOS and settings seemed normal for a PCIe card to automatically start. I put the graphics card back in, powered on, and there was display so I assumed my graphics card was working. I installed Windows, etc., but when I went to install drivers for my graphics card it was undetected.

I'm worried that I might have a bad PCIe slot. I've tried reseating it twice, it's definitely connected to my PSU (the GPU fans are working), and I'm not sure what other setting to change in BIOS. Any suggestions are appreciated, thanks!

CPU: i5-3570k
Motherboard: Z77A-G45
GPU: Radeon HD 7770
RAM: Kingston HyperX 8GB
HD: WD 1TB
PSU: Ultra LSP750

Try the other PCIE slot, and dissable the HD graphics in the BIOS.

You could have a bad PCIE slot or a bad GPU. Make sure all your connectors are pushed in and realy check to make sure the the GPU is all the way pushed in
and try a new Power connector if you have one

If your not putting your GPU in the first PCIE slot your computer defaults to that one.

Good Luck

try updating the BIOS of your mainboard.
your gpu seems find...just check to see if Windows can find the card from the device manager.
also update Windows to see if that works.
