Hello, im currently using AMD RADEON HD 7670M on my laptop TOSHIBA SATELLITE L850, 4GB OF RAM, I5-3210M, Windows 8.1 64 bit and I've encoutered problem like drivers stop working on amd (TDR). I've already done troubleshoot like checking the temp of my gpu and cpu, also all of my drivers are updated but still the problem persist, So I've checked your website for updated drivers and I saw two possible updated drivers, The first one is "Catalyst software suite and second one is Radeon software crimson edition beta". My question is do I need to install this both drivers on my laptop? or do I need to install one of those drivers? and if I had to choose one? what should I install in my pc?. thank you.
