Here are some of the things you should try, in order of ease and likelihood of solving your problem. • Turn off your screensaver (or switch to using the “blank” screensaver), and see if the problem goes away • Switch your video driver to “vesa” in /etc/X11/xorg.conf (see this section for detailed instructions), and see if the problem goes away • Reboot and choose “memtest” from the grub menu; run the memory test, and see if all your RAM tests out ok. If not, time to get some new RAM chips (or maybe just reseat the old ones).
