Have you tried downloading the latest drivers from their website? what Power Supply are you running? you can do a check with gpu-z or in the bios if the card shows up there then its definitely a driver problem i suggest you remove any old drivers from your p.c as they might be causing conflict with the new ones and have your anti virus software disabled when installing the drivers. . If i were you id just reinstall my OS (operating system e.g windows 7)
I have deleted all old drivers. I have downloaded the correct drivers for the 7570, I have reinstall the operating system. The power supply is a 750W from Dell. The original card was an Invida. What next?
