My wife has a Sony Vaio computer that is just over a year old that has Vista. It has worked well but for about the last three weeks it is acting up. Every other day or so while she is on it (always plugged in) for a varying amount of time it will just shut down. No warning, no error messages just basically turns off. The computer sometimes can be on for 10 minutes or hours and I check it for heat but that cannot be it as it is cool as anything. I turn it back on and sometimes it will load up normally and sometimes as it is starting up again it will shut itself down again suddenly as it is going through the process. After a few attempts it will eventually get back to the actual windows screen and work normally until the next shut down a day later or two. I have run a virus scan and it didn't come back with any issues or spyware. I also took it to Geek squad since we have the two year protection plan on it, they blamed it on heat and dust but since it is still doing it that can't be true.

If anyone has any ideas please share, she is going crazy.
