Situatie
“My computer is slow” is not a diagnosis. Before buying more RAM, replacing the SSD or reinstalling Windows, determine which resource is actually causing the bottleneck.
Start with Task Manager
Press:
Ctrl + Shift + Esc
Open the Performance tab.
Observe CPU, Memory, Disk and GPU usage while reproducing the problem.
CPU Bottleneck
- If CPU utilization remains near 100 percent, identify the process responsible.
- A temporary spike is normal.
- Constant high CPU usage during light workloads is not.
- Potential causes include background applications, malware, updates, browser workloads or simply an underpowered processor.
Memory Pressure
- If physical memory is almost completely occupied, Windows may have to rely more heavily on virtual memory.
- That can cause noticeable slowdowns. Check which applications consume the most RAM before assuming more memory is required.
Storage Bottleneck
- A computer can feel extremely slow when storage latency is high.
- Older mechanical hard drives are especially noticeable during Windows updates, application launches and multitasking.
- An SSD is one of the most significant upgrades for a PC still running Windows from a mechanical disk.
Thermal Throttling
- A processor can reduce its clock speed when temperatures become too high.
- Dust, blocked ventilation, failing fans and cooling problems can therefore appear as performance problems.
Background Software
Check:
Task Manager → Startup apps
- Disable unnecessary programs.
- Do not install “RAM cleaners” or random registry optimization software as a first response to performance issues.
Malware
- Unexpected resource usage can also justify a malware scan.
- Use a reputable security solution and keep Windows patched.
The Golden Rule
- Measure first, change second.
- Replacing random components is expensive troubleshooting.
- A few minutes examining CPU, RAM, disk activity and temperatures can tell you far more than simply describing a computer as “slow”.
