Hello, I just changed my GTX 570 (defective) for a Gigabyte Radeon HD 7870 2GB. I uninstalled my NVIDIA drivers with driver sweeper and all. When I open my computer, my card is detected as Standard VGA and when I install the ATI drivers, my card is not detected either. The ATI Technologies folder is still empty. I even tried to reset my BIOS.
My motherboard is a MSI Z77A-G45 (pci-e 3.0 compatible)
Is this a DOA card? Thanks for your answers.
I have some news, but I will anwer your questions before.
I have a CoolerMaster 750W, so this is more than enough. My rail is at 12.038 volts and I have plugged the 2×6 pins connectors.
I have done something so install it, tell me if everything is ok. I went into device manager and right clicked on the stardard VGA and went to properties. There, I chose to manually install the drivers from a file on my PC and I selected the 12.8 drivers from Radeon. Now it is detected as Radeon HD 7800 series. Is this how it is supposed to be? Nothing detect it as HD 7870 precisely. I can open my games, but I do not have Catalyst center, etc.
What do you think?
