If your computer turns off immediately or even within a few seconds after it is turned on, there could be several possible issues. To go on, we recommend going through each section below to assistance find a solution to your problem.

Circumspection

Some of the steps below require you to open the computer instance. While working in your machine, e'er exist aware of the dangers of ESD.

Loose cable

Make sure all cables inside the computer instance are firmly attached to the motherboard and each component. Check the IDE cables and SATA cables, which are connected to the hard bulldoze, CD or DVD drive, and floppy bulldoze (if present). Check both ends of each cablevision and make sure they are firmly attached to the component and the motherboard. Turn on the figurer and test to see if this resolves the issue.

Tip

Sometimes, the best manner to verify a cable is not loose is to disconnect and reconnect (reseat) the cable on both ends.

Surge protector issues

Surge protectors and battery back-up units can go bad over time, causing reduced power menstruation to the computer. As computers require a specific amount of power to operate, too not bad a reduction tin force the computer to shut 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. Turn on the computer to see if the trouble persists. If the computer stays powered on, the surge protector or battery back-up unit of measurement is bad and needs to be replaced.

Electric short

An electric short in a estimator, which may cause ability issues, happens when pieces of metal cause a path for electricity to flow through that shouldn't exist. Computers are full of screws, equally they agree nearly every internal component in place, and from time to fourth dimension, they can come loose. Lift your computer and gently rotate it while gently shaking it from side to side. If you hear what sounds like small rocks banging around, you lot likely take loose screws inside the case. Open the computer up and remove them.

Memory issue

Verify the memory modules are properly seated in the memory slots on the motherboard. To do this, open up the reckoner, remove the memory modules from their slots, and gently reseat them. It also is important to note that retentivity modules are installed in pairs, and sometimes in matching slots, which are designated past matching colors. Make sure the modules are firmly seated and the clamps on both sides of the modules snap into identify. Plug in the ability cord and turn the computer on to see if the issue is resolved.

Power supply issues

Ability supply voltage switch

The power supply voltage switch, a minor red switch on the back of the power supply, may be on the wrong setting. If this switch'due south setting is not correct for your country, your figurer may automatically ability downwardly. The first matter to do is to consult the Voltage Valet website to discern your land's correct voltage settings. So, make sure your power supply voltage switch is ready accordingly.

Possibly defective power supply

Verify the power supply is functional. A faulty power supply can result 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 computer retailers sell power supply testing units for under $20. In the event of a bad power supply, the just remedy is to supersede information technology with a new one. Fixing a power 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 chop-chop. Because of the potential of damage to hardware that overheats, if the computer exceeds a gear up temperature, it is automatically turned off.

Motherboard outcome

The last matter to check is the motherboard; even so, this tin can exist rather difficult since the issue could be anywhere in the circuitry. A faulty, failing, or malfunctioning circuit or component (eastward.thousand., capacitor) can cause the computer to shut off immediately or not turn on at all. If none of the recommendations higher up help resolve the outcome, we advise sending the estimator to a repair store or replacing the motherboard.
