Hi, I have a problem with my notebook, it has switchable graphics, an Intel HD + ATI HD 5470, it works fine with the Intel HD, but when i try to switch to ATI, my screen turns off and my notebook restarts, but when i connect it to an external screen i can see the BSOD crash report, and i dont know what to do :/, i´ve downloaded bluescreenviewer, and it says something about an archive named atikmpag.sys, i will appreciate so much your help
have a nice day, ohh i forgot, my system specs are:
Windows 7 Home premium (preinstalled) x64
Age of system: 3 years
Core i5 450M 2.4Ghz
ATI HD 5470 + Intel HD graphics (switchable)
HP DM4 1190la (Notebook)
Thanks
