Rather than disconnecting the outputs from the power supply. After a move, when you plug the AC power to the power supply again, turn the computer ON. If you get the glitch, unplug the power supply [from the AC line] for about a minute, then plug it in again and turn it on.
You didn't really explain, in sufficient detail, the indications when the bad startup happens. Do fans run and keep running hard drives run, power on LED light etc, etc??
About a week ago, my computer would just TURN OFF by it self without warning. Than it would later just Flicker ON and FLICKER OFF right away (total time between ON and OFF: 0.5 sec) At first I thought it was OVER HEATING but later I found out that I needed a new POWER SUPPLY to accommodate the needed power. SO, I purchase a 400 watts Antec Power supply and replace it, it works!
The concern that I have is that after all of this, some time my computer would turn on but it will not recognize any thing (IE Monitor, Mouse). It does usually occur when I move my computer around the house. This was resolve by disconnecting all the power cables from to power supply to the computer components (IE mother board, hard drive).
What is the problem with this? And how can I prevent this?"
