My Dell Inspiron mini's BLACK SCREEN OF DEATH

Hello,

I have a dell inspiron mini notebook. My problem is that it won't have a display when I turn it on. The power indicator would indicate it's on but all I could have is a black screen. I've tried turning it off and on for several times and luckily it has worked for me twice. But the next few days, when I turned on my notebook, after I've entered my password, the screen just went fuzzy like lots of color pinks and then stays like that forever. I would like to know what I could do with this on my own. The last thing I wanna do is to bring it to a technician. I don't have enough money for repair.

Hope this would help. Thanks!

PS: My OS is Windows 7 starter..
