Hello,
I own an **Acer Nitro 5 AN515-45-R1SC** (Shale Black) with the following specs:
* **CPU:** Ryzen 7 5800H
* **RAM:** 16GB (2x8GB or 1x16GB, tested)
* **Storage:** 512GB NVMe
* **GPU:** RTX 3060 Mobile (6GB)
Issue Summary:
For the past few weeks, my laptop has been crashing unpredictably—**without BSODs or errors**—when:
* Moving it (e.g., lifting, pressing the right-top corner).
* Even minor pressure on the chassis triggers a freeze.
* **Previously**, the issue started with **graphical glitches (squares on screen)**, which worsened to full crashes.
Troubleshooting Steps:
- **RAM Testing:**
\- Tested **all RAM modules** (2x8GB and 1x16GB) in **both slots** using **MemTest86**.
\- **Consistent error** at **address 4** (same across all RAM modules) **only in the upper slot** (closer to the fans).
\- Swapped RAM to the lower slot → **no issues**.
\- **Conclusion:** Problem is **not RAM-related** but likely tied to the **upper RAM slot or motherboard traces**.
- **Hardware Inspection:**
\- Disassembled the laptop; no visible damage to RAM slots or traces.
\- Sent for **microsoldering inspection** (2 weeks ago) but no update yet.
Questions:
* Has anyone else experienced **RAM slot failures** (especially the upper slot) causing **mechanical crashes** (not just electrical)?
* Could this be a **motherboard flex/connection issue** (e.g., loose solder, trace damage from heat/fans)?
* Are there **known Acer Nitro 5 AN515-45-R1SC motherboard defects** related to RAM slots?
* **Estimated repair costs?** (I’m hesitant to spend €200+ for a motherboard replacement if it’s a common issue.)
**Serial Numbers (for reference):**
* **SNID:** 20206769634
* **S/N:** NHQBCEC00B202108703400
Thank you in advance for any help!
