or you can just help a few newbies if you know something

you should just go buy an ati card and forget about this, all you are gonna achieve if you go down this path is waste your time and a lot of electricity that is gonna be paid by someone else.

here is a solution:
open a video on youtube, right click on the video and select settings, click the monitor icon on the bottom left and uncheck "enable hardware acceleration", flash doesn't do well with mining, even if you don't get a crash you  get substantially less mhash/sec when watching flash video if hw accelration is enabled.
