[QUOTE="westom, post: 1423589, member: 138367"] I could state exactly what was defective IF you had posted important numbers. Apparently your power system has failed. The power system is many components - not just a supply. One minute with a $7 meter means numbers from six wires. Then what has failed is quickly obvious. For example, what decides if a power supply can power? The power controller. What would damage that? Well, a protector too far from earth ground and too close to a computer can bypass superior protection inside the PSU. Connect a surge to earth destrictuvely via other parts including the motherboard. Then the power controller would fail and not power on the PSU. The one minute of labor can be defines only if you are interested. Most who work on computers are too afraid of the $7 meter. Ironic since iPads and iPhones are many times more complex. Without numbers, then do the other choice. Just keep replacing good parts until something works. Also called shotgunning. You have two choices. Replace only the defective part. And actually learn how computers really work. Or shotgun. Without hard facts (ie numbers from a meter), then every reply can only be 'replace this or maybe replace that'. Meanwhile, learn something from your experience. Read the manufacture specifications for that protector. It did exactly what the manufacturer said it would do. As with the meter, you must ask to learn more and to learn of solutions that can make future damage virtually impossible. [/QUOTE]
