mobility radeon 9700 problems: strange lines and graphics ..

Archived from groups: alt.comp.periphs.videocards.ati (More info?)

Hi group,

i bought an ACER Aspire 2023 with an ATI mobility radeon 9700 128M.
Using a 3d application (a game), the graphics starts to had strange
errors like lines and dust in game, but exiting the game the problem
persist in the windows (XP) gui to.
I tried to reinstall the video drivers, the mother board drivers,
slowing down the AGP, but nothing change.
The only way to make the noise disappear is to set the hardware
acceleration to zero. But in this case no 3d application runs, like my
graphic card doesn't exist.

Does anybody had the same problem?
Any suggestion please?
Is possible to be an hardware problem?

thanks very much,
violink

Perhaps the GPU is faulty and/or overheating.

downloading the core and memory the problem persist and in some case goes worse.
the screen becomes unreadable...
so it is an hardware problem,
don't you think?

thanks for your help,

I purchased a laptop from CyberPower and it came with the ATI Mobility
Radeon 9700. I too am having the exact same problems, it doesn't
happen all the time, but give it time and theres vertical strips of
light black pixels coursing on my screen. Maybe it is an overheating
problem I'll have to try some underclocking, but this is really
angering. Card runs good, but this is unacceptable, you have to
reboot when this happens.
