PSU failure probably caused CPU shutdown. Issue resolved.
PSU failure probably caused CPU shutdown. Issue resolved.
Recently during attempts to start my machine, it hasn't managed to display the DRAM warning indicator. I haven't found a solution yet and would value some guidance on next steps. I've shared the hardware details and the actions I've taken so far.
PC specifications: CPU - AMD Ryzen 9 7900X, Motherboard - Asus TUF Gaming B650M-Plus, RAM - G.Skill Flare X5 32GB (2 x 16GB), DDR5-5600, GPU - EVGA FTW3 ULTRA GAMING GeForce RTX 3080, Storage - Western Digital Black SN850 1TB M.2, Power Supply - Thermaltake Toughpower GF1 PE 850W.
Background: The system has operated for almost two years before these problems started. Before powering off, the machine failed to boot the following day with the DRAM warning on. A restart didn<|pad|> page after that didn't help.
Troubleshooting attempts:
- Checked DRAM on another machine; it worked.
- Tested RAM in each slot individually; no success.
- Removed the GPU to isolate the issue; system still didn't respond.
- Verified connections and cleared CMOS; problem persisted.
- Tested with a different motherboard (MSI PRO B650M-P); still failed, showing CPU and DRAM warnings.
- Had the PSU inspected; motherboard appeared intact.
- Brought in a shop for CPU replacement, received RMA instructions. Returned the board and waited for a new processor.
- Installed the replacement CPU; DRAM warning reappeared.
- Tested with a friend's system; it booted normally, indicating the CPU issue isn't the main cause.
- Current uncertainty: whether the problem lies with the PSU or the motherboard.
Advice needed: If anyone has tips on deciding which part to return for RMA, I'd be very grateful. Both the PSU and motherboard are still covered under warranty.
Thanks for the update Neutraliz. It seems I found the root of the problem. The power supply was unstable, leading to brief power drops that interrupted memory training. After replacing it, the system started working again during training, which likely triggered further issues. The new CPU didn’t seem to fix the situation on its own. It might have been a sign that the shop didn’t fully diagnose the cause or didn’t test another processor. Regarding the PSU replacement, the new model and cable layout appear different—possibly from Thermaltake. It’s tough to verify data or opinions when modifications happen, which can affect testing results.
