How do I fix the black screen on my PC?

If while working on your PC, the screen suddenly goes black, don’t panic! The solution is right here.

Black screens are caused by various things.

*You have installed applications that you do not know and you have not uninstalled them.

*After an update

*While surfing on NNe, you have visited unsecured sites.


Enough talk, here is how to fix your PC:

Always have a reflex of restarting your PC( by pressing the power button for a few seconds), it can fix everything. Otherwise, when you start your PC, press the f8 key.

There, the screen gives you several choices.

“Start Windows in Safe Mode” is a solution.
If you are allowed to do this, you must

  • access your control panel (“Start”, then “Control Panel”)
  • then select “Backup and Restore”
  • “Restore system settings or your computer”
  • There you will have the opportunity to restore your computer
  • The latter restarts and carries out the restoration.

Sometimes, the safe mode is not proposed, it is “System Restart” that is proposed instead.
Choose this option and let yourself be guided, you will not lose your data in any case, your operating system will simply return to a previous version at the system level which will correct the errors generated in the meantime.

Also, a simple restart of your computer is sometimes able to correct the problems related to a black screen.

System reinstallation

In the worst case,

insert your Operating System installation CD/DVD in your CD/DVD drive or on a USB key.

Start your computer by pressing the F2 key to access the BIOS, go to the “BOOT” tab

and choose the boot on CD/DVD drive.

Your computer will then reinstall your operating system.
To keep your data, choose the upgrade and not the reinstallation of the system, they will then be accessible in a folder named Windows.old located in your hard disk.

In case of a black screen, don’t panic, the solution exists, follow these instructions and restore your computer. If you are not confident enough, call the PC repairman.

Why does my computer turn on so slowly?

There are several explanations.

The hardware obviously plays a role.
Your computer may not perform “naturally”. The components that make it up make it not fast, the speed at which it processes data is low. If it is a fixed one, you can eventually change some components. It seems to me that it is the processor and the RAM that are involved in this work.
SSDs are known to be fast as well.

There is a software part.
The more programs you have running at startup, the longer it takes for the computer to turn on. Don’t hesitate to prohibit programs from launching at startup if they are not needed right from the start (a word processor doesn’t need to load at startup, it can wait to be requested without any problem for example).
For Windows 10, just search for “startup” and the computer will suggest “startup applications” which will open a settings page. There you can disable unnecessary programs. Be careful not to disable all those you do not know, some are necessary (mouse, keyboard, sound, graphics etc.). Only deactivate programs that you know and are sure that they will not create problems if they are deactivated.

Memory can also affect boot speed.
The fuller the computer’s hard drive is, the longer it may take to boot up and launch applications, especially if it is not defragmented regularly. The computer will look for information where it is on its disk(s), so if it needs some information on one side and the rest on another, it will take a little time to go and find it.

Malware can be a factor.
Some viruses or Trojan horses are known to slow down computers. So always keep an active anti-virus program up to date. Remember to scan regularly and be careful when downloading anything.

Computers are slower when they are hot! The components should not exceed a certain temperature. So when it’s hot, the computer is deliberately putting less strain on its components to avoid overheating. Think of dusting it once a year at least at the level of the fans (if it is a fixed one, you can even open it to dust delicately inside). There are dedicated dry compressed air cans. If you have a laptop that heats up, there are fans created specifically for them.
Also check with professionals to change the thermal paste regularly.

It is probably a machine running Windows.

At the time I was at work, the norm was to reinstall Windows every year, because the performance was going down with time. But I admit that it was not yet Windows 10.

Try to see if there are any Linux groups in your city/neighborhood/school, and try the performance of your machine by booting on a Linux USB key.

How to fix a computer that turns on but does not start Windows 10?

Beware of the EFI boot that is sometimes damaged, or after an update of the system, it is necessary to launch windows in repair mode and repair this boot (unfortunately you need to know a little about the subject).

Repairing an EFI boot loader on a GPT hard drive for Windows 7, 8, 8.1 and 10 on your Dell desktop computer

If, at boot time (after reboot), some keys (related to the brand/version of your Windows and your PC like ECHAP/SUPPRIM/F2,F8,F9,F10,F12) do not allow to boot Windows in repair mode and restore the operating system “without erasing data”, You need to make a bootable USB key or an external repair disk with another PC. A version of Windows 10 USB to reinstall your PC is available for free on the Microsoft website or on the website of the brand of your computer (windows OEM version). Use USBIT to make your key from the downloaded image. Then boot on this key in order to repair or reinstall Windows without deleting data (if the hard disk is not broken, otherwise same procedure but after replacing your hard disk by a new one, preferably a 256Gb, 512Gb or better 1Tb SSD disk).

All the procedures for booting into safe mode and repairing and restoring and downloading images of Windows are available on the Microsoft site and other computer experts.

Indeed, it is quite vague. Are you able to boot with an installation key, for example, of Linux, or of WIndow, made on another computer? Are you able to access the configuration screen for disks, memory, boot, etc (also known as BIOS)? Do you have an error number displayed on the screen?

If you can boot from a USB stick, are you able to see your hard drives that you know are in your computer?

To me, the two most likely things are:

  • A defective hard drive
  • An installation of Windows that has gone haywire

In both cases, you should be able to boot from a USB stick (or CDROM) with something like a Windows installation key – or even better: Linux.

I have often rescued failed hard drives by booting with Linux because Windows didn’t work anymore.

There are too many possibilities to take into account. That it lights up, it’s not bad.

Start by looking if the hard disk light turns on at startup. If not, you should check the BIOS, to see if it recognizes the hard disk (or SSD). In any case, it would be good to check the BIOS settings, to see that everything is in order. If it doesn’t recognize it, then you have to look for the reason.

If you have excluded these errors, then you should check the installation of Windows 10 and/or check the “health” of the disk. If it is not working, then you have to change it.

It is also possible that there is a problem with the integrity of Windows 10 files. For example, the Boot sector has jumped. Then you should reinstall, or repair with a Windows 10 installation support.

If you don’t know how to do this, get help.

Were Windows 10’s tiles a good idea?

Tiles were implemented on Windows with the very forgettable 8!

The worst thing is that the usual location of the start button did not fulfill its role anymore, even though it was always there!

The change was such that many users were more than chilled.

At work I strongly recommended not to put a PC under 8 and to wait for the next version, 8 was a pushover like Vista.

I am used to testing various graphical interfaces under Linux for fun (mine is my favorite but in live CD I try to know!) but I was still dismayed by the interface of 8.
I could not find how to turn off the PC I was presented nor how to get out of it having the command prompt ( CMD) without looking from another PC how to do on a tutorial!!!

In short…

But why was such a horror tested by Microsoft?

Because it corresponded to a project to unify computer environments and the idea was that tablets would take over and the end of the desktop PC.

So a single PC, tablet, phone environment would have been a good idea since the tiles are close to the way of doing things on a smartphone.

There was also the launch of touch screens which would have made this coherence even more valid.

But unfortunately, touch screens didn’t work (too expensive, fragile) and windows phones disappeared.

The public has massively rejected 8 and 10 has found a more classic environment with a touch of tiles that some people like (it’s a quick access to what we use the most, if we configure it correctly).

I don’t mind the tiles in 10, since it’s not opposed to the way I use a PC.

So the tiles of 10 are not a problem.

On how many computers can you install Windows 10 with one key?

In order to use Windows legally, it is necessary to activate it with a license. The license is the famous serial number that we must enter during the installation or activation process to unlock all the functions of the operating system. Depending on the edition of the license (Home or Pro) it has a more or less expensive price. And also, depending on the type of it (OEM or Retail), it will be more or less expensive. But what if we have two computers? Will we have to buy two licenses or will it only work with one?

The first thing to remember is the difference between the two types of license. On the one hand, we have OEM License, cheaper than usual only sold to manufacturers. This is the one that comes by default when we buy a PC and is valid only for that PC. The Retail License is more expensive, and it is the one that any user can buy. It is not tied to any hardware, and if we change computers, we can activate it at other times.

If we are one of those who buy computers already assembled, we will have no problem, because most of them come with factory licenses (OEM). However, if we have one, two or more computers assembled by ourselves or by a store, things change. These computers usually do not have a Windows license. And that’s where the questions start.

If I have a Windows 10 key, can I use it on two or more computers?

Windows OEM licenses are only valid for specific hardware. This is related to the motherboard, and although this allows us to change some components (such as hard drive, memory and even graphics, if you can), at the time the board or CPU is changed, the license ceases to be valid. Hopefully, if we change only the CPU, we can recover it via Microsoft SAM. But if the board dies, the key dies with it.

This means that if we have an OEM license and we have activated it on one computer, it cannot be activated on another computer. However, we could take advantage of the license if we bought an identical motherboard to the one we had. But it has to be identical, even while being tested. Otherwise, it will be invalid.

Obviously, each key is unique. And therefore, we cannot activate it in any other way on other computers.
