Dear people..My computer would turn on as usual until the 'Windows is starting up' screen.. It will automatically turn off and cant be turned on for a couple of seconds (approx 15sec).. It may sometimes turn off at the log on screen or even when the computer has fully started up and is ready to be used.. Without touching the mouse, keyboard or any process, the computer can just turn off by itself..Here are couple of things I have tried myself. I unplugged the wire linking to my hard drive and turned the computer on.. The screen wrote 'Bootup error' which makes sense.. But within a few seconds later, it turned off by itself.. I tried unplugging the main power wire out of the computer for several days.. After which i plugged it back and used it.. Everything worked well even till start up.. When all processes had settled down and ready to be used, i left the computer alone and waited for anything to happen.. True enough, the computer turned off by itself and the screen turned blank with the 'No signal' notice..Please, somebody help me.. Tell me what is wrong with the computer and what can I do to save it.. I thank you in advance..
