Hi, Today when I switched on my computer it began to start up (barely staying on for five seconds) before switching off and repeating the whole process. It does stay on long enough for me to push either esc or f10 and go into computer set up. However i am not too sure what to configure and how and as soon as i exit out of it, my laptop starts the whole on/off process again. I am not too sure about the specs of my laptop, only that it is an Hp and has windows xp. Please, what can i do? I would be forever grateful if someone knows how I can fix this..
