hello. my pc was working fine but the ram got spoiled so i had to change it. now when i did, my aero themes are not working anymore. i cannot not also get to play games.when i go to search for my video card in device manager, my pc says standard vga graphics adapter instead of its real name. i cannot search for my drivers manually because i do not know the model number of my video card because i did not get the chance to know before it changed.all i know is that it needs an ati radeon graphics drivers.i also do not want to search for my drivers automatically.please help what should i do? any answer would be appreciated
