I know the above relate to nVidia cards (what I have) but apparently the problem is not restricted to nVidia.

there are quite a lot of arguments saying what this is about. I'll tell you what I did

go into the BIOS, put your AGP aperture size up to either 128 or 256MB and save it. install all of the latest drivers (like you have done). Hopefully in your drivers in the advanced properties (probably accessible by right clicking desktop> properties> settings >advanced) take down the openGL and direct draw PCI texture memory buffer to about 5MB. that should sort out most of the problems. I've noted that if you have a power supply less than 350W upping the power supply can help. Apparently getting better cooling can also help.

some of this lot may also interest you
