Yea, and be charged with harassment.
That could be your number for all we know, and besides that we have experience to the contrary. Besides clearing may lead to issues down the road. Chances are that it will have no aid at all in this case, not any other case involving a HDD unless it is a SATA/IDE mode issue. Your computer knowledge comes into serious question with this suggestion too, this on top of your statements about burning the drive out with different SATA controllers and SATA versions. I think you have successfully trolled this thread, but may actually believe that it may help.
The CPU issue with the BIOS was most likely a temp sensor that clearing the CMOS cleared the error log and reset it. This is the only thing I can contribute to causing it to fix the issue, unless it was an unstable OC, or some setting in the BIOS was messed with to cause system instability. One thing is for sure, if it was just dusty and no settings were messed with, removing the CPU would not require a BIOS reset. These are the facts.
