I bought a new pc like 3 month ago, it's a HP CQ2911EL with windows 8 64 bit and graphic card ATI Radeon HD 7310 pre-installed. The problem is that when i try to install drivers the installation start but after that pc doesn't request the usual reboot after installing graphic drivers. I install also utility drivers from HP support site but they doesn't work; so i contact the HP support center that answer me i've to wait the drivers of my graphic cards are fixed. After 3 months i can't use my new pc at max performance. Have I to change my OS or my graphic card? Could you help me please?
