Causes identifiées

4 causes
#1

Processus d'arrière-plan excessifs

80%

De nombreux programmes peuvent s'exécuter en arrière-plan sans la connaissance directe de l'utilisateur, consommant des ressources système comme le CPU et la RAM. Cela peut ralentir considérablement les performances de l'ordinateur.

#2

Infection par logiciel malveillant

70%

Les virus, les logiciels espions ou d'autres logiciels malveillants peuvent exécuter des processus cachés qui consomment des ressources système et compromettent les performances. Ils peuvent également voler des données ou endommager des fichiers système.

#3

Espace disque faible

60%

Quand un disque dur est presque plein, le système d'exploitation a du mal à effectuer des tâches essentielles comme la création de fichiers temporaires, ce qui entraîne un ralentissement notable.

#4

Pilotes obsolètes ou corrompus

40%

Les pilotes sont des logiciels essentiels qui permettent aux composants matériels de communiquer avec le système d'exploitation. Des pilotes obsolètes ou corrompus peuvent entraîner des problèmes de performance et de stabilité.

Solutions recommandées

8 solutions
💡

Check Task Manager/Activity Monitor

95%Official
Open Task Manager (Windows) or Activity Monitor (macOS) to identify and close unnecessary background processes.

🤖 AI Analysis

"The user is experiencing a general slowdown, and identifying resource-hogging applications is a primary step in diagnosing this. Chrome and Word are mentioned as slow, which could indicate they are consuming excessive resources or are being impacted by other processes."

💡

Disable Startup Programs

85%Official
Prevent non-essential programs from launching automatically when the computer starts.

🤖 AI Analysis

"Unnecessary startup programs can significantly impact system performance from the moment the computer boots up, contributing to overall slowness. This is a common cause of a computer becoming slow over time."

💡

Free Up Disk Space

80%Official
Delete unnecessary files, uninstall unused programs, and empty the Recycle Bin/Trash.

🤖 AI Analysis

"While the user has 50GB free, which is generally a good amount, a full disk can still cause performance issues. This solution is still relevant as it addresses a potential, albeit less likely given the stated free space, cause of slowness."

💡

Run Disk Cleanup Utility

75%Official
Use built-in tools like Disk Cleanup (Windows) to remove temporary files and system junk.

🤖 AI Analysis

"Temporary files and system junk can accumulate and consume disk space and system resources, leading to a slowdown. This is a good general maintenance step for performance issues."

💡

Run a Full System Scan

70%Official
Use reputable antivirus and anti-malware software to perform a thorough scan of your system.

🤖 AI Analysis

"Malware or viruses can severely impact system performance. Since the slowdown occurred recently and without new installations, a hidden infection is a plausible cause."

💡

Update Antivirus Definitions

65%Official
Ensure your antivirus software is up-to-date to detect the latest threats.

🤖 AI Analysis

"Outdated antivirus definitions might mean the system is vulnerable to new threats that are causing the slowdown. This is a supporting step to solution 5450."

💡

Update Device Drivers

50%Official
Check for and install the latest drivers for your graphics card, network adapter, and other key components.

🤖 AI Analysis

"Outdated device drivers can sometimes cause performance issues, especially if they are related to components used by the slow applications (e.g., graphics drivers for Chrome). However, it's less likely to be the primary cause of a general slowdown across multiple applications without recent hardware changes."

💡

Use Driver Update Software

45%Official
Consider using a reliable driver update utility to automate the process.

🤖 AI Analysis

"This is a more automated approach to solution 5454. While potentially helpful, it's less direct than manually checking and updating key drivers, and the relevance is lower as driver issues are not the most probable cause of a recent, general slowdown."
