Bottom Computer Screen

Bottom Computer Screen, it was not just in the computer, and there may be more I have not seen in there, this is the bottom screen that keeps out most bigger dust and sucks airflow up through the computer, and yes, having an open screen top it blows the tainted air right into this room. This is the type of whatever the fuck it is causes back pain and I suspect also causes the difficulty in urination. Which now is gone for the most part. Still things I have not found, and of course the poison closet where I store all the stuff [like my poor S.G. AXE] I have not cleaned yet, and this damn keyboard even after boiling all the keys 3 fucking times and cleaned with that and vinegar, salt and baking soda , plus washing the mechanical part with hot water,it still is not completely safe.
