Hi I have the same Laptop and same problems, from date of purchase before Tiny went bust, I replaced the fan 3 months ago with a more powerful one, (just found one that fitted) and it sees to stop the overheating problem. i still get crashes but only when i use lots of graphics, I know i have a problem with the S3 twister driver as i have uninstalled the original and used a different one that seemed to work fine, but now i cant find the good version. I am looking now for an updated driver or maybe i can get a new graphics card installed. Hope this helps, if you also have a graphics problem please let me know. (screen just stops, need to power off and restart) STEVE
