Hello,
I just bought HP Pavilion 14 N037-TX
Intel Core i5-4200U 1.6GHZ
4 GB DDR3 RAM
AMD Radeon HD 8670M 2GB DDR3
The notebook already had Ubuntu (uninstalled now) and then I installed Windows 8.1 64 Bit.
I installed the necessary drivers from http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?os=4158&lc=en&cc=id&dlc=en&sw_lang=&product=5448937
However, the driver for AMD Radeon didn't work, http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=ob-126598-1&cc=id&dlc=en&lc=en&os=4158&product=5448937&sw_lang=
The installer failed to install AMD Catalyst Control Center and it says "Application Install: install package failure!"
And then I took a look the installation log, it said the installer only install the OEM but not the Catalyst Control. I keep looping install-uninstall the driver but it's always gave the same result.
I already tried some driver from AMD, this one: http://support.amd.com/en-us/kb-articles/Pages/latest-catalyst-windows-beta.aspx
and then this one: http://www.driverscape.com/download/amd-radeon-hd-8760
and this one too: http://www.amd-drivers.com/download-RadeonHD8760-graphics-driver-for-Windows8-64bit.html
and now I am using this one: http://support.amd.com/en-us/download by detecting my OS and automatically install the best driver according to AMD, it has 'Mobility' on it's name.
The problem is, those drivers was succesfully installed the Radeon on Device Manager, but not in dxdiag. The dxdiag still shows that I am using the Intel HD Graphic instead the AMD Radeon 8670M. The catalyst control center won't let me see what GPU is used for power savings and high-performance mode. The dxdiag keep on showing the Intel HD Hraphic whether my notebook is plugged-in to power source or on battery, the Switchable Graphics just did not work as expected.
I already look for an answer in so many forums with similar problem, but the problem still persist.
I am sorry for my bad English, hope you guys can help me, thanks in advance.
