2days ago i shut down my laptop VAIO VGN-FW490J, half an hour later i turned on and windows did not start, the windows logo stuck on screen and then my laptop became hot and hotter while windows did not start and still windows logo stuck, i tried any other option even windows disk, it did not boot. i just saw black screen after press any button to boot from disk. i don't have back up disk unfortunately. what's the problem? just tell me, i need laptop for my M.A course
