I just purchased a Zotac GeForce GTX 770 graphics card as an upgrade. I followed the instructions to a T, uninstalled my previous card, turned the power off, as well as unplug the power supply, removed it, and replaced it with this bright shiny new one. I plugged in the PCI Express, but only one. After I connected the power and turned it on, the screen said to connect the PCI Express, so I turned it off again and connected both. This time it started up as normal. Windows starts up, and it's immediately evident something is wrong with poor video quality. There is no "New Hardware Found" bubble that pops up as it should, and Device Manager lists the display adapter as the Standard VGA Graphics Adapter. Everything is plugged in properly, and both fans are running on it, so I assumed it was working, but my computer doesn't notice the card at all.
My previous card was MSI R5670-MD1GD3 Radeon 5670
And my current hardware is
Power Supply- CORSAIR CX series CX600 600W ATX12V v2.3 80 PLUS BRONZE Certified Active PFC Power Supply
Processor- AMD FX-8120 Zambezi 8-Core 3.1GHz Socket AM3+ 125W Desktop Processor FD8120FRGUBOX
Motherboard- ASUS M5A78L-M LX PLUS AM3+ AMD 760G + SB710 Micro ATX AMD Motherboard
