Need more information.

When it "on and off"'s, when you turn it on, does it turn off immediately? or after a short time?

When it does normally boot, does it stay on? Or does it turn off again.

Possible causes: Power supply, Hard Drive, Motherboard, Charging pin, RAM
(as you can see, this is why we need it narrowed down, be as exact as you can)

The thought occurs to me...what appeared to be a problem with the LCD...may have been much more serious.

I think you need to have a conference call with your friend.

I agree with Louis. Perhaps the computer was not such a good deal afterall.

yes when i turn it on, it does off immediately(its very quick) and it goes so many times.but luckily when i got it boot up and successfully login to windows,
i can use it for hours or more. the only problem now is the 'turn on' process. any idea?

The above listed info. Try removing some components one by one and see if you can get a successful boot. Replace the RAM, pull the hard drive, try powering on without the battery. If those fail, your motherboard is likely dead.
