The main reasons why a computer might be slow include:
- Not restarting the computer regularly, which causes background processes to accumulate and hog resources.
- Having too many programs or browser tabs open simultaneously, which uses up RAM and processing power.
- Rogue programs running in the background consuming CPU and RAM without the user's knowledge.
- Hard drive or memory being nearly full, reducing virtual memory space and slowing down processing.
- Too many programs launching automatically at startup, overloading the system.
- Presence of viruses or ineffective antivirus software that lets malware run and degrade performance.
- Running in low power mode, which limits processing power to save battery.
- Excessive visual effects consuming system resources.
- Hardware issues such as overheating, outdated drivers, or aging components.
- Accumulated dust inside the PC causing overheating and reduced speed.
To improve speed, it is advised to restart the computer regularly, close unnecessary programs and tabs, check and manage startup programs, clear hard drive space, run virus scans, set power mode to high performance, and consider hardware upgrades or cleaning if needed.
