kernel-power 41 BIOS is up to date. All drivers are up to date. Seems like when you do something to your system it behaves for awhile. I see comments that someone did something and it seems to have solved the problem, just wait it will getcha. I put a new drive in, nothing on it yet, just a replacement for one that crashed. System has been good for three days now, but I know that it will sneak up and get me when I least expect it. Wish Microsoft would look into this as it really sounds like their problem. I was thinking of buying a new system, but how do I know that I will not have it with the new one. Linux is looking better and better.
