How to Stop Your PSP from Crashing or Rebooting

PSP crashes (black screen, freeze, auto-restart) usually stem from hardware aging or software conflicts. Systematic fixes:

1. Overheating (Very Common)

• PSP-1000/2000/3000 run hot. Dust clogs heatsink.
• Fix: Open shell, clean heatsink/fan with compressed air + isopropyl. Replace thermal paste (Arctic MX-4 / NT-H1) on CPU/GPU.
• Play in sessions: 60–90 min breaks. Avoid charging while playing.

2. Memory Stick Issues

• Fake/cheap MS Pro Duo (common on eBay) have bad sectors → crashes.
• Fix: Format in PSP (Settings → System Settings → Format Memory Stick). Test with h2testw on PC. Use genuine Sony/SanDisk or high-end Samsung.

3. Battery Degradation

• Swollen or high-internal-resistance batteries cause voltage sag under load → reboot.
• Fix: Replace with genuine Sony extended battery (1800/2200 mAh) or high-quality aftermarket (Cameron Sino). Avoid $5 generics.

4. Software / CFW Conflicts

• Outdated CFW (Custom Firmware) / plugins (CWCheat, PSPStates, etc.) conflict with newer ISOs/PSN games.
• Fix: Update to 6.61 Infinity / LME-2.3 (permanent CFW). Disable all plugins in VSH.txt / GAME.txt / POPS.txt in seplugins/. Re-enable one by one.
• Corrupted ISO/CSO: Re-dump from UMD or verify SHA-1 via Redump.org.

5. Hardware Faults

• Power Board / Fuse: F1/F2 fuses on mainboard blow. Test continuity.
• NAND Degradation: Bad blocks cause boot/module load crashes. NAND dump/restore via Pandora/Service Mode.
• Loose Ribbon Cables: Screen, Wi-Fi, UMD drive ribbons. Reseat carefully.

Quick Diagnostic Order

1. Remove Memory Stick → boot to XMB. Stable? → MS issue.
2. Remove Battery → run on AC only. Stable? → Battery issue.
3. Disable all plugins → test. Stable? → Plugin conflict.
4. Clean heatsink + repaste → test under load.
5. If all fail → motherboard / NAND fault.

PSP-1000/2000/3000 are repairable; Go (PSP-N1000) and Street (E1000) have non-user-replaceable batteries and tighter tolerances.
