Fix a Dead Power Supply Using a Hair Dryer (Reflow Trick)

My Hp Pavillion a805n desktop stopped functioning properly after I temporarily disconnected the system from the power supply. At first, I thought the machine was dead (i.e. Power Supply Failure). However, I discovered a little trick using a Hair Dryer to bring the machine back to life. I thought I'd share to help other distressed Hp owners out there...

Summary: A quick & temporary fix for those with a blinking/flashing power supply. 
Risk: When dealing with heat and computer components, there is always a risk of something going wrong. Perform this procedure at your own discretion.
