Defraggler64.exe
After I downloaded the latest version of Defraggler (Solved Boot Time Defrag), I decided to do both an error checking process (Check For Errors/Recover Bad Clusters) and defrag. So, I scheduled a defrag on the next boot. I figure that the process for both will take awhile, so I planned to do it overnight. Next morning, I discovered something off: my computer. That's not right... so I turned on my computer and everything seems fine... until 5 minutes later and the computer automatically shuts down. It keeps on repeating the process. On the off (well lucky) chance seeing what was up with the computer, I checked the my CPU's tempurature (Using Core Temp RC3). Each core temperature was heating up, fast. This has never happened to me before. Then it hit me to just open up Defraggler. It says that it has multiple tasks running, and if I would like to close them. I clicked Yes and the temperature of the cores cool down, all is well, I decide to just do a normal defrag right there and then. All of a sudden, the temperature spike back up. I stop it, and the temperature still goes up. I close the program, then start it again, all to receive the previous message I got earlier. The only way to truly stop it was to just uninstall Defraggler.
I hope this gives you enough information to resolve this issue. I don't want to continue using Defraggler until this is fixed. As this bug can damage my (or any other) computer.
