My laptop is a toshiba satellite A300-1m1 and I'm using an ATI radeon mobile HD 3470

Here's an example of the problem: http://img69.imageshack.us/img69/7011/29467894.jpg

I've tried turning it off to cool off, uninstalling and then updating the video drivers, turning the color color quality settings from 32 to 16 bits ( they disappeared but came back when i opened 1080p video files )

Any ideas?

I've recently had some intermitent artefact problems like that:

Win7 x64 Home Premium, Nvidia 9800GTX+, (likely to be) latest gfx drivers.

Reboot solves mine. I actually found mine to do that when I try playing this transcoded m2t file (unsuccessfully). The PS3 can play it through the server though.

My graphics card had that problem previously too, when it was still covered by warranty - I just returned it.

Is yours under warranty?

Probably not

Memory error, your gfx chip is overheating, and if overheated enough, it might have inflicted permanent damage.

Which is prolly why the mem error keeps showing up under varying circumstances

Are you talking about vRAM error, or sys RAM error DS?

I ask because the suspected reason that happened to my gfx card was the RAMsinks falling off.

Speedfan says it's fine though

vRAM, sysRAM would produce very different, and far more annoying errors.

And I don't think there is any test you can run to verify what the memory is doing, but "artifacts" on screen almost always indicate an overheating problem.

The checkerboard one you have is definitly a memory error, and since your system isn't locking up hard when it happens (which it should), I'd say it's permanent damage....sucks ;[.

does it give you a temperature readout from the GPU ?
