Stripping on your computer.

The first thing you should do is to remove the case system, put on a non-conductive surface and disconnect all the components of the motherboard with these exceptions

CPU (and radiator fan) A single stick memoryVideoPower supplyPower button

Mean no readers, no devices, no additional ports rien.Ce tests two problems at the same time. They are the possibility of some devices preventing the tensioning system and the possibility of the motherboard short-circuit on the case in some way (aka, an impasse which should not be used).

Make rapid elimination (only if the system is completely omitted to give any power at all), find where power button connects and short of these two pins for a moment with what you side conducteur.Un screwdrivers, knives, coin or anything metal work. If the system runs, you need a new power button. (If your system is already spinning place, you can skip this step).

If the system fails to be outside of the case, here are two things you need to do. First, make a Visual inspection of all capacitors on the motherboard. These are the things to look at the battery.What you'll see is any fluid leakage from the top or bottom, any "confused" anywhere on them, or if they are swelling on top or on the sides.

While you're driving around bad capacitors, take a look at the ATX power connector.Make sure you have any brand of dryness or watch fondu.Si anything one of these features, your motherboard is almost certainly your problem.If all worldwide ok, test several times, with each module memory individually at each location (it means nine trials for three sticks of memory on a plate with three locations!).

If the system powers eventually places, you have found good memory - probably your only problem - and you probably fait.Remettre simple version in case and sécuriser.Si powered up once more, go to step 9.

If not, you must remove once more and investigate the setup of your motherboard standoffs and ensure that nothing is touching the motherboard where it shouldn't be touché.Après this and all is well with the principles in the case, go to step 9.

If it fails to power in place with a configuration of the memory of the case, we know that it must be the processor, memory, video, motherboard, power, or any combination thereof.
