I have recently bought a HD 5770 ATI video card replacing my current 8800GTS and burnt 275GTX video cards. I uninstalled everything nvidia related in my computer (windows 7 64bit), turn PC off then replaced video card... turn pc back on and all I would see is a blank screen. No bios, no windows, no nothing. I sent the card back for replacement thinking it was a bad card, turns out they tested the card and its perfectly fine and they are now returning it to me. Could someone please tell me what is going on here?

You may want to run driver sweeper in safe mode to make sure everything Nvidia related is gone;
Also updating to the latest bios for your motherboard is a good idea, especially if your HD5770 is PCIE 2.1 and your board is PCIE 1.0.

A 2.1 PCIe card in a PCIe 2.0 or 1.0 slot problem perhaps? Or maybe just a faulty motherboard caused by "burnt" cards.

I have the P5N-E SLI mother board (ASUS mobo) ASUS Radeon HD 5770 Cu Core 1GB DDR5 PCI-E VGA DVI-I HDMI Video Card.

My bios is updated to latest version...

The card says PCI-Express 2.1 but I don't know the mobo version
