how to tell if your motherboard or power supply is bad

When you press the power button and nothing happens, the PC does not turn on one of the most difficult computer problems to troubleshoot.
Possible reasons include almost all possible things that the computer can go wrong.
In most cases, this comes down to a problem with the motherboard or power supply.
In this article, we will discuss the troubleshoot method to determine if there is a motherboard or power issue with your computer.
Checking the power strip is a very easy problem to ignore, but sometimes your power strip or surge protector will trip or turn off.
This is most common when people put them under the table and then accidentally step on them.
This can also happen if the surge causes the circuit breaker to trip.
If your power strip or surge protector has a button or switch, turn it off and turn it back on to see if this solves the problem.
Watch the fan stick to the side panel, or cover the desktop computer and see inside what happens when you press the power button.
The main thing you want to see is if the fans start spinning.
I \'ve seen the computer, the power is broken, the fan moves for a second when you press the power button, and then nothing happens.
Check the fan on the back of the power supply as well as the chassis fan or processor fan to see if the behavior is the same.
If you press the power button and your fan is up and running at full speed, but it doesn\'t seem to have any other features, then this can also be a problem with the motherboard.
When you turn on the computer, listen to any beeps that may be made, as these beeps error codes will help identify hardware issues.
A common quick solution in this case is to unplug the power and then remove and unplug the RAM. (

Most home users may not be able to do this because they won\'t have another power supply.
If you happen to keep a spare one, swap it with the spare one on your PC to see if there is a difference.
On the other hand, you can remove the power from the faulty PC and put it into another computer to see if it works properly.
When the power is burnt out, it really burns out sometimes and you can smell it.
Electronic components have a unique smell of burning.
A common way to remove peripherals to diagnose computer hardware problems is to remove all peripherals such as DVD/CD drives, hard drives, modem cards, sound cards, etc.
All you really need is the processor, RAM, and video to test the functionality.

The Bones configuration runs, closes it, adds a component at a time until the problem comes up again.
Sometimes bad hardware prevents the whole computer from turning on.
I have personally experienced this with a deep-fried modem.
Also check if there is any edema or damaged capacitor on the motherboard, as this is a clear sign of the failure of the motherboard.
The top of the capacitor should be flat.
If you see anything that looks swollen, or leaks any liquid, or has a shell around it, it means they have gone bad.
The real term is \"blown\" capacitors, which means you need to buy a new motherboard.
You can also find the fuse capacitor on the peripheral device, especially the video card. (

In no case should you try to disassemble the power supply in your computer.
It contains dangerous components that novice users don\'t need to deal with, and the risk makes them not worth trying to fix.
Depending on the size, you can start buying new power supplies from around $30.
If you can start your computer, but the motherboard is restarting all the time, be sure to check this article for more helpful tips.
