So Let’s See

Solution 1 – The first step is to do is check your computer externally because sometimes the problem is generating from the shortage of power supply. So check the main power cord is attached to the wall properly or not, if attached removes it and installs it back again and tries to turn on your computer.

Solution 2 – Remove the main power cord from the computer and check for the proper power supply is coming or not. With the help of Multi-Meter Tester you can check the proper power supply is coming regular or not. Your power supply must by continuous or still and also have enough voltage to start up your computer PSU (Power Supply Unit), like you have min 100-110v~ or 200-220v~ to run your computers PSU. Voltage supply is different by the countries, In India the regular power supply is 220v~ but in US and UK the regular power supply is 110v~ So, the computer PSU is also different by the countries. Check your PSU voltage compatibility and then check for correct voltage supply is coming or not.

Mine was supported 230v and the powers supply coming from my computer’s power cord is 223v that means I don’t have any power problem and my power cord is also work perfectly. If you don’t see any power supply coming from your power cord that means you have faulty power cord, replace it with new one.
Solution 3 – After that external checkup your computer still doesn’t turn on that means you have an internal hardware problem in your computer. So, this time we have to open the computer case to check where this problem is coming from.
The First internal checking checkpoint is PSU, open your computer case from the right side and check the PSU is working or not because 60% of this problem is coming from the faulty PSU. Here is link to show you how to check your PSU is working or not-

If your PSU doesn’t work that mean you have faulty one in your hand so replace it with new one. If you’re PSU works fine that means maybe the PSU connect socket may loose so, rejoin all the psu connection to the motherboard to make it works this time. If you still don’t see any sign of power that means you have another hardware problem, try our solution No. 4.
