My Windows 7 pc has been shutting itself off randomly for the past 2 days...it was working perfectly before...it got so bad my machine would shut itself down right after typing my Windows Password in to logon to Windows!! ( problem had gotten progressively worse ). Had to use Safe Mode for a while... grrr...
Ran various antivirus/antimalware scans, nothing... deleted Windows Temp folder files, nothing, ran system repair to correct any Registry errors and that did not help... uninstalled various programs trying to get it stable...spent hours and hours on this...
Finally decided to check Windows Event Viewer logs and finally found this error message:
"Adobe Flash Update Service has entered the stopped state"
I had Adobe Flash set to "auto-update" and it launched itself on Windows startup of course, so I used Windows Autoruns utility to permanently disable the Adobe Flash Update Service from launching... BINGO!! PROBLEM FIXED!!
System has been 100% stable after I did that, been up and running for a day now, gaming, torrenting, burning media, whatever... Windows is now happy just like before!
So it was all Adobe's fault, and it is not the first time their stupid Flash player/autoupdate service has borked many an unsuspecting customers machine....
Others have found this same problem too as shown at the bottom of this thread:

Adobe Flash Update

In Reply to: Share which update that was. by R. Proffitt
Adobe issued a bug fix on 8/2/2012.
This was to remedy a severe crash when Adobe automatically updated to a newer version.
Last time I had this happen, about a month ago, same exact symptoms, with Adobe on automatic update. Recovered, downloaded and manually installed that update. Set Adobe to notify only, so when this new update came in, I ran System Restore, just in case. At least I now had an option before I ran the update.
Bug fix was only to fix the severe installer issues if it applied to your system. No Security vulnerabilities were fixed at this time.
If Adobe caused it, this is not a Windows problem or Microsoft's fault. Microsoft cannot fix what they do not own or control.
While that post was made in August 2012, I didn't experience any problems until 2 days ago when Adobe had recently released yet ANOTHER Flash player update that I installed ( auto-notify )... and it sure as hell crashed my system badly...
I wish everyone could just use HTML5 instead of Adobe Flash, I wish Flash would die, but too many websites use it so that is not an option unfortunately...
If your computer has been crashing/shutting itself down recently, just disable the "Adobe Flash Update Service" and you will be fine once again!!
Shame on you Adobe!!!
