I recently upgraded my Windows 7 PC to Windows 10, and it worked, but the screen flicker (groups of horizontal lines that flicker whenever there is any screen movement) is making it close to unusable. I'm wondering what I can do besides rolling back to Win7? I've tried several different AMD drivers as I'll explain below.
Interestingly, I found somebody else with nearly the same HP PC and Radeon HD 7660D with the same problem, who posted a video to YouTube displaying it. Here's the link:
The AMD FAQ says this graphics card is Windows 10 compatible:
Desktop PC: HP Pavilion P7-1240 (approximately 3.5 years old)
Full specs link:
Was: Windows 7 Home Premium 64bit
Now: Windows 10 Home 64bit
Processor: AMD A10-5700
10 Gb Memory
Integrated Graphics: AMD Radeon HD 7660D
Monitor: BenQ G2220HD (I also tried a five year old ViewSonic monitor I had borrowed; no difference)
The display and graphics were fine in Windows 7. Problem started with Windows 10 upgrade.
At first it used the same driver as with Windows 7. I tried using Windows Update and it installed a newer driver "from AMD", dated sometime in 2015.
Problem continued. Rebooted; retried again. Tried updating the display driver again and it said I had the newest.
From AMD, I've tried both of these drivers; problem continues:
Radeon Crimson Edition Beta 16.2.1
Tried both as downloaded from this page:
So I'm currently using the Radeon Crimson Edition Beta 16.2.1.
Windows Device Manager shows:
AMD Radeon HD 7660D
Advanced Micro Devices, Inc
Note the "flickering" happens during login, in any app I try, and with no apps running (just moving the mouse around the screen). However, if I play a YouTube video in web browser or play a local mp4 video, there is on flickering at all! Not sure if that helps.
The one other thing I tried was suggested by the YouTube user in the video linked at the top. I disabled the AMD driver and used 'no driver', and strangely enough, the flicker goes away and I retain the crisp graphics in 1920x1080 resolution. However, after a restart or cold shutdown, Windows 10 starts with a basic windows video driver in 1440x900 or even 1024x768 sometimes. Once Windows is fully up, I can re-enable the AMD driver (I tried this for the Radeon Crimson Edition Beta 16.2.1, the Catalyst 15.7.1 and "Window's AMD" driver), and it will work again complete with flicker. Which I can then again disable .... So unfortunately, not a permanent solution, especially since there are other users of this PC besides me.
Any help, assistance, or suggestions would be appreciated.
