Hi all I bought an used clevo p150em and i got two problems that evolve my GPU 1. sometimes my bios (prema mod 2.15.1227) wont detect my GPU but when it is recognize it works very good, i check the GPU it self there is no physical damage of any kind and connectors are perfect. 2.i downloaded and installed the offical clevo hd7970m driver from there site but when im coming to start it I get an error msg: "Catalyst Control Center cannot be started. There are currently no settings that can be configured using CCC" the version of the driver is 8.00.0891 device manager dose not report any problem with the hardware and maybe flashing a new BIOS will help but thats a little bit tiny advance for me please help me friends, thx in advance
