Question : Toshiba Satellite randomly shuts off and won't turn on

Hello,

I have a Toshiba Satellite A205-S5855 that is almost 2 years old.  Recently it started randomly turning itself off.  I thought maybe it was over heating but it happens first thing in the morning too.  I thought maybe the hard drive was bad but I replaced it last week with a new one and it is still happening.  Now it is so bad it won't turn on.  It gets to a point where it says "Microsoft Corporation" and maybe to the Vista logo then it dies.  

Is it a bad mother board?  What should I do?

Thanks

I would do a ram test, its either a faulty stick of ram corrupting the system or It could need a re-install of your windows.

Download this cd then boot it in your laptop, guide on link also for you in case you do not know how to use it:

I believe that one of your sticks of ram is ejecting corrupted data and that is why it is blue screening and turning off.  Make sure you do an in depth scan for a few hours.
