Troubleshoot Memory
Updated on July 4, 2025
Overview
RAM (Random Access Memory) is essential for short-term system performance. Bad RAM can lead to random reboots, BSODs, or failure to boot entirely.
Tools You’ll Need
- 🛠️ MemTest86+
- 🛠️ HWiNFO64 (for real-time monitoring)
- 🛠️ Windows Memory Diagnostic
- 🛠️ Spare RAM stick for testing
- 🛠️ Isopropyl alcohol & microfiber cloth (for cleaning contacts)
Step-by-Step Diagnostic Process
- Observe symptoms
- Random crashes, application errors, freezes
- Run Memory Diagnostic Tools
- Boot into MemTest86+ and let it complete at least 4 passes
- Log any errors — even one is a red flag
- Check RAM seating & cleanliness
- Power off, reseat all RAM sticks
- Clean contacts with alcohol if needed
- Test with one stick at a time
- Helps isolate bad module
- Try alternate slots on the motherboard
- Use BIOS tools to check frequency/timings
Symptoms & Interpretation
| Symptom | Likely Cause |
|---|---|
| System doesn’t POST | RAM not seated, incompatible |
| BSOD during heavy load | Faulty stick or bad timings |
| Works with 1 stick but not 2 | Faulty DIMM slot or dual-channel error |
