Lookup says it is a Radeon HD6570, but that does not seem to fit with the HD 7600M Series identification.
Anyone who can help out here? Or has an idea how to progress? Or should I just open the hood and look inside?
I have my problem in the meantime solved. I downloaded and used a tool called Driver Reviver. You have a free trial period and that was sufficient for me to solve the issue.
Regardless of which AMD driver you install, the latest Intel drivers must be installed Before the AMD graphics. The latest Intel driver for your laptop is > Download Intel® Graphics Driver for Windows* [15.33]
Go to www.reviversoft.com and download and install the Driver Reviver tool. When you open it it scans all your drivers for outdated ones that require updating. It found (amongst others) outdated Intel graphics and AMD drivers on my laptop. I updated them as instructed, starting with the Intel ones. After restarting the laptop the issue was over.
But , can I found serial key or something to activate it? because it take so long and I have many things that need update.
I only updated the ones that I thought relevant. I did them one by one. Did not take too long. I did not use the tool any further as it served its purpose. Sorry, don't think I can help you any further.
