Tips To Repair Your Computer
Is your computer not powering up? Take the case off the CPU off and check if the lights on the motherboard are on. If there are no signs that power is reaching your PC then the problem could be in any part. It can be the motherboard, processor, motherboard’s memory or the power supply. Most modern computers can power up with just the memory and power supply attached.
You can take a voltmeter and check if the voltage is 3.3. If it is not 3.3 volts this is a bad sign and you need to replace the power supply. In the event that there are different voltages coming out of the power supply this also means the power supply needs to be replaced. In this case it’s best to consult a computer repair expert.
Do you turn your PC on and see that it is powering up and doing nothing else? The hard drive has small connectors plugged into it. Take the voltmeter and this time and look at the pins on these connectors. With the ground connected to the case the voltage should be +5 and +12 otherwise the power supply is bad.
