I have an HP Pavilion M6-1035dx running Win 7 64bit. It has the AMD A10-4600 with Radeon HD 7660G video.
I recently began having issues with video artifacts. There are several independent sections of horizonal lines that flash on and off at random distorting the screen. The individual lines are about 2-2 1/2 inches in length each. They seem to get worse as stuff is happening on screen such as scrolling up and down on websites, typing text on screen, or moving the cursor around on the desktop. The issue happens starting at the Windows login screen, not before during the BIOS screens.
I know it is not a screen cable issue. It happens all the time whether I touch the computer or not. It does not happen as a result of me moving the screen up and down.
Here is the real kicker that has me stumpped. If I go into device manager and disable or uninstall the video card so that the generic video drivers are being used, the display is perfectly fine. The only issue that creeps up is that after a while the laptop begins to heat up far more than if the video card is enabled.
I want to fix this issue because with the generic video active I cannot play some games, fully utilize programs such as Photoshop, and things like the sleep mode in Win. are disabled.
What I have done:
1. Installed newest Catalyst drivers. (Also tried rolling back to old versions of drivers and Catalyst but Windows automatically reverts back to the newest no matter what I try.)
2. Updated BIOS
3. Tried to roll back to previous Windows via system restore but old versions were gone by the time I tried
Is it possible that the 7660g is bad on the CPU? Since it is built in, is there any way for me to test the graphics to see?
I have been dealing with trying to fix this for a while now. Any help is appreciated. I can post a video of the issue on Youtube if it helps.
