If your figurer turns off immediately or even within a few seconds subsequently it is turned on, in that location could be several possible issues. To continue, we recommend going through each section beneath to help discover a solution to your problem.

Circumspection

Some of the steps below crave you to open the calculator case. While working in your motorcar, always be aware of the dangers of ESD.

Loose cablevision

Make certain all cables within the reckoner case are firmly attached to the motherboard and each component. Check the IDE cables and SATA cables, which are connected to the difficult drive, CD or DVD drive, and floppy drive (if present). Bank check both ends of each cable and brand certain they are firmly attached to the component and the motherboard. Turn on the computer and test to see if this resolves the event.

Tip

Sometimes, the all-time way to verify a cable is not loose is to disconnect and reconnect (reseat) the cable on both ends.

Surge protector issues

Surge protectors and bombardment back-upwards units can become bad over fourth dimension, causing reduced ability menstruum to the estimator. As computers require a specific amount of ability to operate, also great a reduction can force the estimator to close downward.

If this situation applies to your computer, unplug its power string from the surge protector or battery back-up unit of measurement, and plug it directly into a wall outlet. Plough on the computer to see if the problem persists. If the computer stays powered on, the surge protector or bombardment back-up unit is bad and needs to be replaced.

Electric short

An electric short in a computer, which may cause power bug, happens when pieces of metal cause a path for electricity to flow through that shouldn't be. Computers are full of screws, as they hold nearly every internal component in identify, and from time to time, they can come loose. Elevator your figurer and gently rotate information technology while gently shaking it from side to side. If you hear what sounds like small rocks banging around, you lot probable accept loose screws inside the case. Open the figurer upwards and remove them.

Retentivity result

Verify the memory modules are properly seated in the memory slots on the motherboard. To practise this, open the computer, remove the retention modules from their slots, and gently reseat them. It also is of import to annotation that memory modules are installed in pairs, and sometimes in matching slots, which are designated by matching colors. Make certain the modules are firmly seated and the clamps on both sides of the modules snap into identify. Plug in the ability cord and plough the reckoner on to see if the issue is resolved.

Power supply issues

Power supply voltage switch

The power supply voltage switch, a small scarlet switch on the back of the power supply, may be on the wrong setting. If this switch's setting is not correct for your country, your figurer may automatically power downward. The first thing to do is to consult the Voltage Valet website to discern your state'south correct voltage settings. So, make certain your power supply voltage switch is set accordingly.

Possibly lacking power supply

Verify the power supply is functional. A faulty power supply tin consequence in not enough, if any, power getting to the motherboard, causing the computer to shut off immediately or not turn on at all. Many online estimator retailers sell power supply testing units for under $20. In the event of a bad power supply, the but remedy is to supervene upon it with a new ane. Fixing a ability supply is not an economical solution, if possible at all.

Overheating

If your reckoner is new or the motherboard was recently replaced, brand sure the thermal compound is properly applied to the processor. If the heat is not being properly transferred from the processor to the heat sink, it can overheat very speedily. Considering of the potential of damage to hardware that overheats, if the estimator exceeds a set temperature, it is automatically turned off.

Motherboard issue

The last thing to check is the motherboard; however, this can be rather difficult since the issue could be anywhere in the circuitry. A faulty, failing, or malfunctioning circuit or component (e.thou., capacitor) tin can cause the computer to shut off immediately or non turn on at all. If none of the recommendations above aid resolve the issue, we propose sending the figurer to a repair shop or replacing the motherboard.
