So a while back when i bought the pc it had the amd radeon 7700 driverand it ran games perfect but it started flickering so i re-installed windows But it gave me a crap driver called the ati radeon 3000 and i cant run anygames, i then asked my friend for a bit of help and he told me to open up my pc and check the graphics card, after doing this i found out i had the amd radeon 7770 X-edition but it wont let me download the driver for this graphics card and i have also tried downloading the amd radeon 7700 driver again, i get a blue screen everytime i try and download the driver saying windows has shutdown to prevent further damage and when i try use the amd auto detect tool it sayes i don't have a amd graphics card.
