Laptop randomely powering off

[Atwooooood]

So the other night i turned on some music in winamp like i do everynight before i go to bed, and everytime i would lay down, not 5 minutes would pass and my laptop would just turn itself off. I had to keep getting up and turning it back on, and it did it like 6 times until i decided to just leave it off.

This morning, it did it about 3 times or so, but so far it has stayed on.

I have a Lenovo 3000 N100 notebook.
1gb ram
pentium dual core 1.60ghz
Vista home premium
the battery in it is completely dead and has been for a while so it is always plugged into the wall so it wouldnt be a battery issue.
if theres anymore specs that you need, let me know.

any help would be appreciated.

Sounds like an over-heating issue

You may need to locate the dissasembly guide and remove all dust
And possibly reseat the CPU (applying new thermal paste)

Actually there are a few links, and info in this guide that may help (including Memtest)
Have a look here: Tutorial: No POST (Power On System Test

so i took the laptop apart and discovered the filter that goes in front of the fan was completely caked with dust so i cleaned that with compressed air and applyed a new coat of thermal compound and so far its been running really nice, just hoping that's the problem and that it doesnt turn off on me again.
