If you are trying to turn on your desktop or your laptop without success, do not despair, there may still be hope.
There are different causes that can cause your computer to not start or stop working, just as there are different solutions that you can implement to get your PC back on as before.
In this article we gather the 5 steps you can follow to make your computer or laptop work again as before.
If you have already followed all the steps and have not managed to make your computer work, you may want to check our guides with the best laptops this year, and with the best cheap laptops in case you don't want to spend too much on a new device.
1. Check the charging source
This is one of the most common problems in laptops. There are several things that may be overcrowded about it: from the use of an incorrect power supply (with the wrong voltage), to a blown fuse in the plug.
Your power supply may also have simply failed or the battery may not work. Verify that the charger is suitable for your laptop, especially that they are from the same manufacturer.
Also check the fuse in the plug. Use a screwdriver to remove the fuse and install a new one, but first try plugging the charger into another socket.
Verify that the problem is not the cable, since sometimes the chargers are damaged. The weak points of the cable are at the ends connected to the central brick, and the part that connects to the computer.
Sometimes, charging sources can also be a problem on desktop computers.
It is worth checking the fuse in the socket and replace it if it is damaged in order to reconnect the computer.
Inside the tower there is also a fuse whose status you can check by removing the cover and opening it to see if this is really the reason why your computer does not turn on.
Another common problem is that even if the PC is turned on, it turns off unexpectedly while it is being used.
If the LED is on and shows that the power is coming, make sure the power button is connected and working properly.
2. Check the screen
Try disconnecting all external screens, including projectors and monitors to make sure they are not preventing your laptop from starting Windows.
If the power LED on your computer turns on and you can hear the hum of the hard drive and fans, but there is no image on the screen, try to darken the room to the maximum to see if there is any image on the screen very dimly.
It is quite common to think that the laptop does not start, when in truth the only problem is the screen and not the computer itself.
If there is a dim image, perhaps the Windows login screen, it is likely that the screen inverter has failed. This component is responsible for changing the direct current that comes from the battery or the power supply to an alternating current required by the display.
Replacing an inverter is not a very complex task if you are skilled with screwdrivers, but it is crucial that you acquire the right replacement part. Also, since investors are not exactly cheap, you cannot afford to be wrong.
If your laptop seems to boot well, but there is no image at all, it could be a failure in the LCD panel. It is possible to replace a laptop screen, although it is a difficult task, and the screens are expensive.
That is why if you are facing an old laptop, it is worth buying a new one.
There is not much you can do to repair a damaged PC monitor, although it is much easier to replace in this case. You can use a different cable, or even replace the entire monitor to see if that is the problem.
3. Remove any connected USB or memory cards
If you have already verified that there is no problem with the power outlet or with the screen of your computer or laptop, and your computer hangs before it starts Windows it may be because of the USB or devices that you have connected.
In this case, it is common to find the message Operating system not found. Most of the time, this means that BIOS is configured to attempt to boot from removable storage drives (including memory cards).
It may also be some DVD that you have forgotten in the Blu-ray drive, so do not forget to check it.
4. Try a rescue disk
If you are seeing different messages with errors and there is no memory card, external hard drives or DVDs inserted and the computer still does not boot, try using a rescue disk.
If you have it, you can use the Windows DVD, and if you cannot download (using another computer, obviously) a rescue disk image and burn it to a CD or DVD or pass it to a USB stick.
Then you can start the system from the rescue disk and try to solve the problem with Windows.
If it is a virus that is causing the error, use an antivirus rescue disk, as this will also include the option to scan damaged files and remove the malware
5. Start the computer in safe mode
Even if you can't start your computer from Windows, you can do it in safe mode. Press the F8 key at the same time that your computer tries to start and a menu appears offering you the option to start in safe mode.
If you manage to start in safe mode, you can undo changes that may have caused the failure by causing your computer or laptop not to turn on.
You can try to uninstall any new recently installed program, uninstall a disk that has been recently updated or create a new user account in case the current one is corrupt.
6. Check if the hardware is defective or if incompatible
The fault may reside in a new memory or hardware that you have recently installed and that because it is not compatible or because it is defective, it is preventing your computer from starting.
If your motherboard or motherboard has an LED reading that shows the POST codes, look for the manual on-line to find out what the code that appears is.
It can often be complicated for a built computer to boot. The best advice here is to disconnect everything except the minimum necessary to start the BIOS:
- CPU (with heat sink connected)
- Graphics card (if there is a graphics output on the motherboard, disconnect all connectable graphics cards).
- A memory (remove any other and leave only the rod in slot 0)
- Power supply
