Hi,
first of all here are my specs which I bought last year (sorry the words will be in german)
Operating system: Windows 7 Home premium 64bit German
RAM: 16GB (2x8 GB), 1.600 MHz Dual-Channel-Speicher
Graphic card: AMD Radeon HD 7970M Grafikkarte mit 2 GB GDDR5
Intel HD Graphics 4000
disk: 500 GB Serial ATA Festplatte (7.200/1min)
Processor: Intel Core i7-3610QM (6MB Cache, up to 3.3GHz w/ Turbo Boost 2.0)
Now to my problem,
Sometimes when I was playing a game and having for example a website open at the same time, the screen suddenly flashed and a windows message appeared saying "driver has stopped responding and has recovered" and had to restart what ever program i was running. This did not happen a lot. Yesterday the same thing happened but for the first time, the screen turned black yet the laptop was still running, i was forced to turn it off, and so i did. Once i turned it back on, my resolution was set to 800x600 and so i set it back to 1600x900 and went on to the Device Manager to see that there was no option which i used to have, "Display adapter", not even my default Intel HD Graphics 4000. At the same time, a new device was being installed and it turned out to be this Intel HD Graphic yet my AMD graphic still did not appear. I tried reinstalling the whole ATI program, and in the end of the installation is said "Installation complete (warnings occured during installation) View logs for information". When I opened the logs there were no problems under "problems" and everything that appeared on it seemed to have installed successfully.
I'd be grateful if you could help me. Thank you
