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

any ideas?
 
As an experiment, download RadClocker

and *downclock* the core and memory to about half speed. If the problem goes
away, it's probably overheating. If the problem persists, most likely the
memory is bad.

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 Mobilit
Radeon 9700. I too am having the exact same problems, it doesn'
happen all the time, but give it time and theres vertical strips o
light black pixels coursing on my screen. Maybe it is an overheatin
problem I'll have to try some underclocking, but this is reall
angering. Card runs good, but this is unacceptable, you have t
reboot when this happens
 
I'm having the same problems with my ATI Radeon Mobile 9700. Exactl
as he describes. I've been through different drivers, screwed wit
the settings for OpenGL and Direct3D, tried playing games on lo
graphics, it still happens, although I'm not sure it ever has o
Brothers in Arms. But the rest of my rts games like Stronghold 2
Empire Earth, and Civilization 3 suffer from this problem. Hopefull
someone here can help us out
