When it shuts down, it takes about 2-3 seconds and then it turns itself back on and does the whole thing over again. It tries to do this a couple of times before it gives up.
I've tried turning it on with the battery in, without the battery and and only the charger, and with both the battery and charger in. All the same.
My fan is btw replaced with one I bought on Ebay, and have been working great ever since I got it. I have opened up my computer several times, and nothing have ever happened before.
I dont get as far as to the boot screen; my screen doesn't seem to be turned on at all when I press the start button. I've tried resetting the bios by removing the battery and unplugging the charger and then holding down the start button for about a minute, but nothing happened.
Edit: I btw run Vista.
Edit 2: A boot cd did not work, btw. Doesn't seem like the cd player is turned on at all.
