Electrical works

This afternoon I pull out my CPU unit and cleaned it. I checked some parts and its wiring. I dismantled some of its parts and cleaned it outside by using a vacuum cleaner. I also repair its blue lamp and right now its all working. I thank my daughter Keisha for helping me fixing my desktop. I also taught her how to check broken wires by using my multi-tester device. I am not a computer technician but since I am so interested in those things I learned it by watching some of my friends who knows electronics but I have some electrical background as a professional auto-diesel mechanic.
