I've observed and heard cases of home owners complaining of sickness where no apparent cause was immediately known. Later, after investigation it was found their home was the cause. It needn't be an old home but even new homes as long conditions were meant, the problem can exist. Here is an interesting site that provides the types of molds and their sources for interesting reading. As always the repair is easy but troublesome as large or whole segments of home has to be removed and then repaired.
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
