Query: Blue Screen restart nightmare

I've had this computer for about one year. Only one or two blue screens and restarts the first month. Now I average about 4 or 5 per day under heavy usage. I've spent ~$200 trying to fix the problem. Do some research on the internet. You'll find hundreds of people with the same problem. Even so, Toshiba pretends the problem doesn't exist. I will NEVER buy another Toshiba product.
