0Matériel PC CPU RAM Mise à jourDes moyens simples pour rendre votre PC plus rapide

There are lots of tips and advice out there on the internet about how to tweak the performance of your PC. Some of them have some useful tips, but the vast majority are of very little use, either because they are for the wrong operating system, ou qu'ils ne s'appliquent pas à votre configuration, ou parce qu'ils sont tout simplement faux. Quand quelqu'un apporte un PC vers moi et dit sa trop lent, avant que je leur conseille de le mettre à jour (et c'est toujours une option) I have a quick look for several things that are the leading cause of slow PC performance. Sur 90% of the time carrying out the various steps detailed below results in a substantial improvement and a happy PC user.


Some of the advice provided is very easy to follow. Some requires a little bit more technical competence. If you’re not sure what you’re doing it’s better to stop and ask than to mess up your system even more.

1. Anti-Virus / Firewalls etc.

There is an abundance of security solutions out there. Some are better than others. The most common ones often come bundled with new PC’s. They may be effective, but in my view thecureis almost as bad as thedisease”. Suites by grands noms (par exemple. Norton, McAfee) take an appauling toll on the performance of your PC, and come with a yearly renewaltaxto boot. The first thing to do is replace them with an excellent and free solution with a low impact on system performance: Microsoft Security Essentials

  • Télécharger Security Essentials for your version of Windows from Microsoft
  • Uninstall your previous anti-virus suite: Go into control panel and then openadd/remove programs” ou “programmes et fonctionnalités” (depending on your version of windows). Look for and uninstall any products related to: Symantec, Norton, McAfee, Sophos, Kaspersky, AVG, Avast, BitDefender, Panda, Trend Micro.
  • Remarque – WikiPedia provides a full list of antivirus software
  • Install and update Security Essentials

1b. Security

Whilst we’re updating your anti-virus protection it is worth updating various other pieces of software to reduce the likelyhood of any nasties getting onto your PC

2. Check for nasties
In my experience the large majority of typical 3+ sont infecter l'an vieux PC avec une sorte de méchant, even if they have had anti-virus software installed. Before going any further it is worth checking for and eliminating any malicious programs.

  • Run a full scan with Microsoft Security Essentials and remove anything it finds
  • Télécharger System Ninja and in the process manager tab run theMalRun Destroyer” outil
  • If you are still suspect there may be malware present, essayez d'utiliser l'un des free online virus scanner (par exemple. HouseCall)

3. Remove old software that you no longer use

If you have old software that you never used still installed it is worth removing it. It is occupying disk space which causes a small reduction in performance, and it is also possible that it has services or start-up utilities that were installed with it that will be running on your system all the time using resources for no good reason!

  • Open control panel and then openadd/remove programs” ou “programmes et fonctionnalités” (depending on your version of windows).
  • Go thru the list and uninstall any programs that you are confident you no longer need or use

4. Clear disk space and temporary files

Over time all PC’s build up a collection of unnecesary files. Ces accès disque lent, and Windows response times. They are easy to clear automatically. La première chose à exécuter est un outil Microsoft intégré, and then to be thorough, also download and use a free utility

  • Cliquez sur Démarrer, all programs, accessories, system tools, nettoyage de disque (ou début utiliser: Exécuter et tapez cleanmgr)
  • Attendez que l'analyse soit terminée
  • On Vista and Windows 7 click theClean up system filesbutton on the window that appears
  • Cochez toutes les options et cliquez sur OK
  • Download and install CCleaner
  • Download and install CCEnhancer
  • Run CCleaner
  • Click Analyze
  • Cliquez sur Exécuter Cleaner
  • Si vous n'avez pas déjà, télécharger System Ninja
  • Run System Ninja and use theJunk Scanner

5. Exécutez une défragmentation de disque

This probably wont do a great deal for performance overall, mais si vous avez libéré beaucoup d'espace disque avec des étapes 2 ou 3 then it should improve windows boot-up time and may make a small difference to responsiveness. Some versions of windows carry out scheduled defrags anyway in which case this wont make any difference, but it certainly can’t do any harm.

  • Ouvert début: all programs: accessories: system tools: défragmenteur de disque
  • Follow the instructions

6. Install or update chipset drivers

Beaucoup PC I have encountered over the years have used very outdated, or simply haven’t had any chipset drivers installed at all. Having very old chipset drivers, or relying on the generic drivers microsoft builds into windows can sometimes severely impact performance.

  • Télécharger, installer et exécuter CPU-avec
  • Sélectionnez le “mainboard” languette
  • Prenez note de la première 2 entries in the line “chipset”. These will be the manufacturer and model.
  • If the information isn’t clear or helpful try using Speccy plutôt
  • Most chipsets are manufactured by: Intel, Via, Brouillard, AMD / ATi, nVidia, ULi / ali
  • Go to the manufacturers website and find the “téléchargements” section (clicking on the manufacturer name above should take you to the correct area)
  • Search for drivers appropriate for your version of windows for your model of chipset
  • Download and install drivers if you locate them.
  • Restart windows

7. Installer ou mettre à jour des pilotes vidéo

This is unlikely to make much difference to general windows performance, but it could make a large difference to some applications, especially games.

  • Si vous n'avez pas déjà, télécharger, installer et exécuter CPU-avec
  • Sélectionnez le “Graphics” languette
  • Try to identify the manufacturer and the model name of your graphics chip from the name box, CPU-Z will probably display a logo with the manufacturer name on.
  • If the information isn’t clear or helpful try using Speccy ou GPU-avec plutôt
  • The manufacturer is likely to be one of the following: Intel, nVidia, AMD / ATi / Radeon, Via, Matrox, brouillard
  • Go to the manufacturers website and find the “téléchargements” section (clicking on the manufacturer name above should take you to the correct area)
  • Search for drivers appropriate for your version of windows for your model of graphics card
  • Download and install drivers if you locate them.
  • Restart windows

8. A hardware issue

Your PC needs good airflow to keep cool. Whilst modern PC are unlikely to crash from overheating, they instead suffer severe performance degradation. le CPU will detect that it is getting to hot and will decrease its speed to keep cool. This is an issue that I have very frequently encountered with laptops. Bureau PC sont beaucoup moins enclins, mais beaucoup souffrent encore.

  • Si vous avez un PC de bureau prendre le cas off (unless it is still in warranty in which case skip this tip!) and check for dust or fluff in the large metal heatsink. Also check for dust or fluff inside the case in general. If there is much present I recommend disconnecting the wires, moving the PC to the open air and carefully using a vacuum cleaner (or even better an chiffon d'air / compressed air) d'enlever autant de la poussière que possible.
  • If you have a laptop or portable carefully check the vents in the bottom, side and rear of the casing. With some laptops it may also be possible to remove the part of the casing over the area. Carefully remove any dust or fluff. If there is substantial fluff blocking the vents that you can’t remove try using an chiffon d'air. If this fails consider taking your laptop to a local expert.

9. Startup programs: the most difficult, but most effective

This is the largest and most complicated part of any PC clean-up procedure and as such I have given it a dedicated post. (coming soon!). Pendant ce temps, use the Startup Manager included with System Ninja
