This guide will help you troubleshoot a PC that won't boot at least to the point of loading with "Hardware Problems". Start the operating system. This article is intended for people who have little PC knowledge and are comfortable with opening and working with a PC. If not, I would suggest taking his PC to a qualified PC repair shop.
Let's get started, keep it simple
First and foremost, the simplicity of PC troubleshooting cannot be overemphasized. Looking for the simplest and most obvious solution first can save a lot of time and effort.
With that in mind, here is a list of things to check first.
1. Check the power cord
(cause:Make sure the PC is getting power and the problem isn't just a bad power cord.)
Is it firmly plugged into the back of the PC?
Is it connected to power? If plugged into a power strip --- Is the power strip plugged in and powered on?
Try a different power cord or power strip if possible
Is the building breaker tripped? try another wall plug.
2. Check your monitor
(cause:Make sure the monitor is still working. When you boot your PC, you expect to see something on your monitor, otherwise you might think your PC isn't working when there really is something wrong with your monitor. )
Is the power cord firmly plugged into the back of the monitor? Is the power cord connected to a power source?
If plugged into a power strip --- Is the power strip plugged in and powered on?
Is the monitor powered on?
Is your monitor's video cable securely connected to your PC's graphics card?
Are the monitor contrast and brightness settings set correctly? Try another monitor if possible.
3. Visual check of power supply
(cause:The PC can boot up to the point where the power fails, but it can quickly overheat and stop working.)
Does the fan spin when you turn on the PC?
do you feel hot?
Is there a light that comes on when you press the power button on your PC?
4. Check your keyboard
(cause:You need a keyboard to boot your PC. Most of the time there is a message on the screen that there is a problem with the keyboard, but this is not always the case and the computer may stop booting).
Is your keyboard connected to your PC?
Try a different keyboard if possible.
5. Check your floppy and CD drive
(cause:By default, when your PC boots, it tries to boot from the floppy or CD drive first. If you have a floppy disk in one of these drives, your PC may try to boot from it even though it is not a bootable floppy disk. Most of the time you'll see an error if you can't boot from the disc, but that's not always the case)
Is there a floppy disk in the floppy disk drive?
Is there a floppy disk in the CD drive?
One might think that checking such simple things is a waste of time. Only he can't count the number of times he's been called to fix a single PC
