If the wall out has power, inspect the power line going to the COMPUTER to see if Air Conditioning voltage is making its way to the system unit.Do this with the use of a multimeter.
If there is power, you will need to open the COMPUTER and check for power from the power supply to the motherboard.
When using a multimeter to inspect voltage, make certain you have an excellent ground for the black lead of the multimeter.
One primary trouble you might face with a troubling Power Supply is that it may re-boot the computer with no warning.All info is shed as well as it seems as though this happens at the most awful feasible time.
Booting errors when the computer system initially start’s up is another sign of this element taking place the blink.
POWER DISTRIBUTION PROBLEMS
When the power supply starts to stop working, you could get power at one device and also not another.For example, the Hard Drive might receive power yet the CDROM Drive has absolutely nothing in any way.
One more headache with would create re-booting is the intermittent power mosting likely to the drives or the motherboard itself.Follow the actions below to inspect your power supply must you experience a few of the above troubles.
EXAMINING THE POWER SUPPLY
If the wall outlet, and the power cord excel, make sure the link at the motherboard is secure.Then you might need to encounter the fact that the power supply itself is bad.If you have a Multimeter you could examine the power supply result prior to acquiring a new one.Simply comply with these steps.
Turn off the COMPUTER, but do not disconnect it, open the system device. Establish the multimeter to read DC volts in the next range higher than 12 volts.Locate a power connector similair to the hard disk drive, or cdrom drive port that is unused as well as switch on the PC.
You can additionally unplug a drive adapter and utilize it as well.Turn on the COMPUTER and also put the BLACK probe into the power connector on one of the BLACK wires.Touch the RED probe to the YELLOW cable on the power port.
The multimeter reading ought to be +12 volts Currently touch the RED probe to the RED cord and the analysis should be +5 volts.If no analyses or different analyses happened, you’ll have to change the power supply.If the analyses were correct, you need to inspect the P8 or P9 adapters at the motherboard. These adapters may likewise be called P4 and also P5.To check these adapters, do the complying with …
Insert the BLACK probe into Right into at one of the BLACK wiresCords
Inspect the power mosting likely to the Motherboard connections by inserting the RED probe right into P8 at the YELLOW cable and you should obtain +12 volts.Leave the BLACK cable touching the black wire at the P8 connector.Check the BLUE wire and also the reading should be a -12 volts.
Now move the BLACK probe to the BLACK wire on the P9 connector.Test the WHITE cable by placing the RED probe and also the reading must be -5 volts.Check the RED cords on the P9 connector and you should obtain +5 volts on each red wire.You will not obtain precisely 5 or 12 volts yet the readings will certainly be extremely close, such as 5.02 volts.
If the Power Supply is a few volts off, in either instructions, such as when the RED cable ought to be reading -5 volts yet it reviews -8 volts, or if there are no analyses, change the power supply.
DO NOT remove the power supply from the system device instance when doing these tests.DO NOT execute these tests if you do not feel comfortable.Be certain to get rid of any kind of as well as all electric static accumulation from your clothing and also body PRIOR TO touching any components inside the system unit.And NEVER open up the power supply instance for any reason, considering that high voltage could be present.
