Computer update

Well here's the deal. I was having the "blackscreen " shutdown problem almost every day
Here is a screen shot of my event log

However the company gave no real solutions to this.
My so checked some info and found it could be a power management issue.
So I changed some options suggested especially to raise the CPU Minimum  Processor State Setting to 50%
All seemed to go well and I haven't had a problem for four days, until today. I was using an application that uses macromedia flash 6 and when I closed it the computer crashed. Well I hope that it was just that reason. Let's see what happens from now.
