Advanced Tips to PC Speed Up Like a ProKeeping a PC running smoothly requires more than occasional restarts and clearing the recycle bin. This guide shows advanced, actionable techniques to improve system responsiveness, reduce boot times, and extract the best performance from both hardware and software—without unnecessary jargon. Where applicable, I include step-by-step actions and safety notes.
How to measure current performance
Before changing anything, measure baseline performance so you can judge improvement.
- Use built-in tools:
- Windows: Task Manager (Performance tab), Resource Monitor, Windows Performance Recorder (WPR) and Windows Performance Analyzer (WPA) for detailed traces.
- macOS: Activity Monitor and Terminal tools (e.g., top, iostat).
- Benchmark apps:
- CPU: Cinebench, Geekbench.
- Storage: CrystalDiskMark, ATTO Disk Benchmark.
- GPU: 3DMark.
- Measure boot time with Windows Event Viewer → Applications and Services Logs → Microsoft → Windows → Diagnostics-Performance → Operational.
Record CPU, RAM, disk usage, temperatures, and boot times before making changes.
Optimize startup and background processes
Many slowdowns come from unnecessary programs running at startup or in the background.
- Review startup apps:
- Windows: Task Manager → Startup. Disable high-impact, unnecessary entries.
- macOS: System Settings → General → Login Items.
- Services and scheduled tasks:
- Windows: msconfig or services.msc to inspect — disable only if you understand the dependency (research service names first).
- Use Task Scheduler to remove redundant scheduled tasks.
- Background apps and background data:
- For Windows, Settings → Privacy & security → Background apps — block apps you don’t need.
- Browser extensions:
- Audit and remove unused extensions; they consume memory and CPU.
Safety tip: create a restore point before mass-disabling services or startup items.
Drive health and storage optimization
Slow storage is a major bottleneck—especially older HDDs.
- Upgrade to an SSD or NVMe:
- Replacing HDD with SATA SSD or NVMe dramatically improves boot and app load times.
- Maintain free space:
- Keep at least 10–20% free on system drive for optimal performance.
- Defragmentation:
- HDDs: run defragmenter occasionally.
- SSDs: do not defragment; Windows uses TRIM—ensure TRIM is enabled (

).
- Check drive health:
- Use SMART tools (CrystalDiskInfo, smartctl) to monitor drive longevity.
- Storage cleanup:
- Remove large unused files, old installers, and duplicates. Use Disk Cleanup (Windows) or third‑party tools (CCleaner cautiously).
Memory and virtual memory tuning
Insufficient RAM causes frequent paging and sluggishness.
- Upgrade RAM:
- Adding RAM is one of the most effective speed boosts for multitasking-heavy workflows.
- Optimize pagefile (Windows):
- Let Windows manage pagefile by default, or set a fixed pagefile on a fast drive if manual tuning is required.
- Reduce memory leaks:
- Identify memory-hungry processes in Task Manager; update or reinstall offending apps.
CPU and power settings
Maximize performance while considering thermal limits and power consumption.
- Power plans:
- Windows: choose High performance or configure a custom plan (Control Panel → Power Options).
- Laptops: balance performance and battery life; set plugged-in plan to higher performance.
- Thermal management:
- Monitor temps with HWMonitor, Core Temp. Clean dust, reapply thermal paste if necessary, and ensure good airflow.
- CPU affinity and priority:
- For critical apps, set priority or CPU affinity in Task Manager (temporary) or via scripts for repetitive tasks.
- BIOS/UEFI updates and settings:
- Update firmware for stability and performance improvements. Enable XMP/DOCP for RAM to run at rated speeds.
Caution: Overclocking can increase performance but raises temperatures and may reduce component lifespan. Only overclock with proper cooling and stability testing.
GPU and graphics optimizations
Graphics impacts UI smoothness and game/app performance.
- Update drivers:
- Use official GPU drivers (NVIDIA, AMD, Intel). Clean reinstall if experiencing issues.
- In-game and app settings:
- Lower unnecessary visual effects or use performance modes.
- GPU workload balancing:
- For systems with integrated + discrete GPUs, ensure the discrete GPU is used for demanding apps (Windows Graphics settings or vendor control panels).
- Enable hardware acceleration:
- In browsers and supported apps, hardware acceleration offloads tasks to GPU.
System file, OS, and driver maintenance
A tidy software stack reduces conflicts and delays.
- Keep OS updated:
- Install critical and driver updates; avoid optional updates that you don’t need.
- Clean driver installs:
- Use DDU (Display Driver Uninstaller) for GPU driver issues before installing fresh drivers.
- Repair system files:
- Windows: sfc /scannow and DISM commands to repair corrupt system files.
- Reduce visual effects:
- Windows: System → Advanced → Performance Settings → Adjust for best performance (or selectively disable animations).
Networking optimizations (for perceived system speed)
Slow network can feel like a slow PC.
- Update network drivers and firmware on routers.
- Use DNS caching or faster DNS providers (Cloudflare 1.1.1.1, Google 8.8.8.8) if DNS lookup lag is noticeable.
- Limit background syncs and cloud backups during high-demand tasks.
Security and malware checks
Malware often causes unexpected slowdowns.
- Use reputable anti-malware scanners (Malwarebytes, Windows Defender) for full scans.
- Check for suspicious startup entries, scheduled tasks, or browser hijacks.
- Keep security software updated but configured to avoid heavy, constant scanning during peak work.
Automation and scripting for regular maintenance
Save time and keep performance consistent.
- Scheduled tasks:
- Automate disk cleanup, defrag (HDD only), and malware scans during idle hours.
- PowerShell scripts:
- Examples: clear temp folders, export list of startup apps, manage Windows Update schedules.
- Use package managers:
- Chocolatey (Windows) or Homebrew (macOS) to keep apps updated easily.
When to consider hardware upgrades or replacement
If you’ve exhausted software optimizations, upgrade these components for the biggest gains:
- SSD (NVMe if motherboard supports it) — best single upgrade for general responsiveness.
- More RAM — for heavy multitasking, VMs, large projects.
- Newer CPU/motherboard — for CPU-bound workloads or to enable faster RAM and NVMe lanes.
- Better cooling or case airflow — to maintain sustained performance.
Comparison of common upgrades:
Upgrade | Typical benefit | Recommended when |
---|---|---|
HDD → SATA SSD | Dramatic boot/app load speed | Using HDD as system drive |
SATA SSD → NVMe | Faster random and sequential I/O | Heavy file transfers, pro workloads |
+RAM | Better multitasking, fewer page faults | Frequently high memory usage |
GPU upgrade | Better graphics/render performance | Gaming or GPU compute tasks |
Troubleshooting workflow for persistent slowness
- Reproduce the slowdown and capture metrics (Task Manager, Resource Monitor).
- Boot into Safe Mode; if faster, a third-party driver/app is likely culprit.
- Use clean-boot (msconfig) to isolate startup/service conflicts.
- Check Event Viewer for error patterns.
- Restore system to a known good point or perform an in-place OS repair if needed.
- If hardware suspected, run vendor diagnostics (RAM tests, SMART, CPU stress tests).
Final safety and backup notes
- Always back up important data before firmware updates, driver installs, or hardware swaps.
- Create a system image or restore point when making major system changes.
- When altering BIOS/UEFI or overclocking, make incremental changes and test stability.
