Hello everyone, I purchased a asus hd 7770 to put in my pc toghether with power supply thermaltake 630W berlin ..
To put the psu it took me two seconds and it works fine. However, when I replaced my nvidia gt 630 with the asus hd 7770 screen gave no signal ... (this after uninstalling before the nvidia drivers and used driver sweeper with a lot of registry cleaner ..) now I have reinstalled the gt 630 by installing the latest drivers, there are only those currently, and it works very well ..
I wonder, what did I do wrong? Had to reset the bios? I have not removed all the nvidia?
