I had the exact issue that everyone complained about here. It drove me crazy for about a week. I eventually figured out it was a software issue because I never lost my internet connection in safe mode. I found the issue ultimately when I let my computer disconnect the internet, then shut down, which took forever, and let it go to blue screen, saying driver power state failure and create a dump file. That is when I used Whocrashed and it pointed always to mbamchameleon.sys under driver power state failure. I found that odd as I did not know this file was actually a driver. Like others, as long as I used my machine constantly, it would not crash. Only is left alone for a few minutes. I went through a lot of diag for this. It sucked up a lot of my time. Swapping hardware, updating drivers, etc, before trying safe mode. In any event, after I saw the issue, I found this thread. Just updated manually to the latest version. Hopefully that problem is gone. Thanks for this forum. Much appreciated.
