When did this problem start ?  What have you done different, or has it just sat there stationary and not touched and this started ?

I got it frm my school sicne they dont plan on using it anymore. Though some kids stole the RAM that was inside of it befor ei actually got it, so i tried outting in a 1gb ddr3 stick into it (got no idea how much mhz) but it just starts doing that

From what ive heared though is that it can only run with 2gb ddr3 1066 mhz ram sticks but i dont have those
