Yesterday my Old PC suddenly shut-down and for no reason or whatever I can’t even make my PC to reboot either. So my first suspect was the power supply, but the problem might be with the motherboard, cpu, memory or video card instead. Replacing the power supply without even checking the possible reason is not a modder solution, so to declare it a garbage let do the How-To-Troubleshoot a PC Power Failure by Modder Punker:

Checklist:
1. Make sure the power supply is turn-off and unplug.
2. Ground yourself by touching any exposed metal object or wear a static wrist strap.
3. Open your PC Case.

Let’s begin:
1. Do not expect an ATX power supply to work by simply plugging the power and turning on the switch. ATX power supplies are soft-switched on and off by the motherboard and BIOS. Therefore, you must plug it to a working motherboard with a working microprocessor, memory and video card to work. If your computer does not turn on after you turn on the power switch, it may not necessarily mean a dead power supply. The problem might be with the motherboard, microprocessor, memory or video card instead. You must examine all these components to isolate the problem.

2. The most effective technique to tell if a power supply is causing any problem is to use a different one to see if it solves the problem. If everything works with a different power supply, then the new power supply is most likely the troublemaker. Alternatively, you can plug the new power supply to an existing, working computer to see if it works there.

3. Computer cases are highly modular. If your computer case is still under warranty, you don’t have to send the entire case back if only one part of it is defective. For instance, send only the power supply back for exchange if only power supply is dead. The same is true for the face panel and cover. This would save you quite a bit of shipping and sometimes downtime.

4. More than 70% of all computer problems are related to cabling and connections. Ensure that you all the power plugs are connected firmly, including power connections to your motherboard and all the drives.

5. Make sure the cooling fan inside the power supply is working all the time. Reach out to feel the fan behind your case often. Clean the fan if necessary. If your case feels warmer than room temperature, check the power supply fan first. Most power supply fans are difficult to replace. You are better off to replace the entire power supply since the new one comes with a brand-new warranty.

6. Most cases and power supplies these days are made and tested in China and other Asian countries where 220V electricity is used. Desktop computer power supplies do not switch the power voltage automatically. (Most notebook computers do!) If the factory forgets to turn the manual switch back to 110V for the North American market after testing, the power supply would appear DEAD if you use on a 110V-outlet. Therefore, always check the voltage setting on the back of a new power supply FIRST if it appears dead.

Here you go, if all this thing is all set and done and your PC still won’t able to reboot. I hereby declare that your PC Power supply is nothing but a garbage.

Please consider checking your local recycle center for proper disposal of your old Power supply and other PC components. Bestbuy accepts almost all type of electronics stuff for their disposal and it’s a free service, check your local store for more details.
