A slow desktop doesn't always need replacement. Often, targeted software fixes and affordable hardware upgrades can make it feel new again.

Software Speed Fixes (Free)

1. Disable startup programs: Task Manager → Startup → disable unnecessary items 2. Disk Cleanup: Run Disk Cleanup and remove temp files, Windows Update cache 3. Defragment HDD: Only for HDDs (never SSDs). Defragment & Optimize Drives tool 4. Malware scan: Run Windows Defender full scan or Malwarebytes 5. Uninstall bloatware: Remove pre-installed trial software 6. Visual effects: System → Advanced → Performance Settings → "Adjust for best performance"

Hardware Upgrades (Best ROI)

HDD → SSD upgrade: Single biggest speed improvement. Boot time drops from 2 minutes to 15 seconds. Cost: ₹1,999–₹4,999 (including cloning). RAM upgrade: 4GB → 8GB or 8GB → 16GB. Eliminates "disk thrashing". Cost: ₹999–₹2,999. Thermal paste: If CPU throttles due to heat, repasting adds 10–15°C headroom. Cost: ₹499.

When to Replace vs Upgrade

If your CPU is older than Intel 6th Gen or AMD FX series, upgrading requires a new motherboard + CPU + RAM bundle. At that point, a new system might make more sense. Consult with Xigox for honest advice on upgrade vs replace.
