One of my friend tried to make my laptop (toshiba-satellite-bought in 2002) run faster and did something in control pannel. Now istead of running faster it got crashed. * when i turn on it blinks as TOSHIBA for 2-3 sec and then gets vanished and only light blue screen appears. * hard drive light gets solid after sometime (10-15min) but i can hear crackling sound for about 20-30 min * after that nothing sound comes * when i try to shut down by pressing power button it doesn't work launa ho sathi haru ho help garnu paryo......yo ke dasha lagya ho semester sakine belama. bholi presentation garnu parne, sabai slide haru tehi cha, jump drive ma save pani garina......malai ta runu na hasnu banai sakyo bhanya...............
