Steps to fix the computer not showing up

Hello guys, once I obtained the case, it did not present up, I clicked on the facility button and it did not begin up or the machine simply beeped on the speakerphone. Right here, I’ll information you thru the steps to repair a pc that does not present up for brand spanking new pc technicians.

I’ll divide it into 2 instances: Urgent the facility button the fan doesn’t spin, and urgent the facility button the fan rotates however doesn’t present up.

+ Case: Press the facility, the fan rotates however doesn’t present up.

To start with, whenever you obtain the case that the machine doesn’t begin up, it’s worthwhile to ask the client fastidiously what’s incorrect with the machine, when, when it’s utilizing the machine or on account of {an electrical} quick… Asking fastidiously will assist appropriate the illness and sooner. For instance, if a buyer says there’s a quick circuit, we’ll consider the facility provide, if rain water hits the case, we’ll consider the mainboard being touched by water…
Strive plugging the consumer’s case into your monitor, to rule out display screen failure, or an issue with the facility provide on the buyer’s house.
Open the case and take away peripherals resembling DVD drive, LAN card, Onerous drive (the onerous drive is a very powerful, as a result of when testing the machine, simply plug it in after which pull it out many instances to burn the onerous drive -> lose knowledge. ). Then plug within the energy and press the facility button to examine if the machine activates. Bear in mind to plug the VGA cable into the proper VGA port on the machine, some machines connect a separate video card, once we plug the monitor wire into the onboard VGA port, the machine won’t present up. As well as, it’s vital so as to add a keyboard to know if the machine is up or not by urgent the num lock key to see if the sunshine is on.
The machine nonetheless doesn’t activate, see you probably have a discrete and onboard video card. If the machine has an onboard VGA however the buyer makes use of a separate video card, then you may take away the cardboard and fasten the wire to the onboard VGA port. Normally do to this step, the machine is up, as a result of a lot of the illnesses are attributable to the long-term use of the video card, or the chip is lifeless.
The machine nonetheless doesn’t activate, then you definitely take away the Ram fully, connect the exterior speaker. Can purchase a motherboard take a look at card will diagnose sooner. Then click on on the facility and take heed to see if the exterior speaker sounds “tick ! tit ” to report a ram error, or the primary take a look at card has jumped a couple of codes. If sure, then the fault lies within the Ram, strive one other Ram is OK.
The machine nonetheless doesn’t sound on the speaker, the illness is worse, you continue to go away it, however strive one other supply, simply plug within the 20 pin (or 24 pin) jack and 12v jack after which activate the facility once more. If the machine beeps, exchange the facility provide and also you’re finished.
Eliminated all peripherals, eliminated Ram, tried one other supply, however nonetheless nothing. Now you take away the CPU fan fully, take away the CPU holder and mount it up and down a couple of instances => the aim is for the CPU to contact the socket pins. As a result of it may be used for a very long time, grime and mud could make contact with the legs not good, due to the cleansing means of attaching the FAN to the latch, it takes some time for the CPU to be on one aspect. Or the machine is used for a very long time to open the ball lead on the foot of the socket.
After 6 steps on the machine nonetheless not up, you fully take away the mainboard to check. As a result of it may be on account of tightening screws, altering ram, eradicating the FAN after which urgent it down too onerous, making the machine not contact the mass. Whether it is up, you assemble the mainboard into the field in line with the proper operation within the article: Word when assembling the machine into the field .
Lastly, examine and restore the mainboard, perhaps as a result of the capacitor is dry for a very long time, lifeless ic ram, chipset …

+ Case: Urgent the fan button doesn’t rotate.

Take away the peripherals after which click on once more. There are a lot of instances the place the onerous drive is burned, the LAN card or the sound is brief, and the facility can’t be pressed.
The ability button itself is broken, or the wire related to the facility button is bitten by the mouse. The ability button pressed many instances too onerous to interrupt the leg, so it couldn’t contact the facility wire on the mainboard. You fully take away the P.ON energy wire related to the mainboard panel and click on it immediately on the mainboard by utilizing a screwdriver or tweezers to the touch it.
Resulting from quick circuit, dry capacitor, lack of voltage to the P.ON pin, exchange the great supply to rule out this case.
The final step is as a result of the mainboard is shorted, 32,768 KHz quartz lifeless, mosfet quick, Vcore quick or lifeless chip Nam, IO chip. We simply must examine and repair the mainboard cannot get the supply.
