3D graph.manipulation slows my computer until turn off & on again(reboot doesnt work)
I've got a really annoying problem and I would need some help.
I've got Fedora Core 2 running on a laptop P4 with an Intel 845GV chipset compatible with VGA UMA. I have used linux on this laptop since December, but now that I need to use mathematical 3D graphics manipulation (with Matlab and other software) I find that, after some time of manipulation, the computer slows down considerably. If I try, for example, to move any Nautilus window (without any other program running), the frame moves very slowly and after the cursor. When I reboot the computer, the memory test at boot goes much much slower than usual. For restoring to the "normal" speed, I have to shut down the computer and start again.
Please, I would be really interested in any suggestion.
