We're looking for the part causing the issue.
You experience sudden crashes while playing intensive games, especially PUBG. The PC freezes despite lights and fans working, but the display remains off. Troubleshooting shows no display, only CPU and memory indicators on the motherboard. Restarting requires turning off the power supply. Crash timing varies—sometimes during gameplay, other times in lobby or when opening the app.
You've tried several fixes: updated GPU drivers, reinstalled GPU, reset connections, changed power limits, used different BIOS settings, and even attempted underclocking. A temporary fix came from adjusting the GPU clock offset and setting a lower power limit. CPU and memory lights stay on, but GPU temperatures are normal during play.
Your RAM appears to be failing, possibly at 3000MHz or lower than rated. XMP settings cause restarts but not stability. You've tried higher voltages, manual timings, and even 3000MHz operation without issues. The issue seems more related to the power supply unit (PSU). You're considering replacing it and need recommendations for a reliable, affordable replacement. You also plan to replace RAM soon, as the current one is likely faulty, and you're unsure if it's the motherboard or RAM itself. You're cautious due to limited local repair options and mixed confidence in your troubleshooting steps.
It might be the PSU, but what model is it? If the RAM is still functional but performance drops, it’s likely only slightly affected. Checking the DRAM voltage in BIOS and pressing + once or twice could restore operation. Adjust the VOLTAGE accordingly.
You attempted to increase the DRAM voltage. Does this only occur in games? Have you run any stress tests like Cinebench, Heaven, or Membench? Such crashes could stem from any component. I’d run these tests to pinpoint the issue. If all fail, inspect the PSU, open HWinfo without any processes running, and verify the voltages—especially 5V, 12V. A slight change is normal, but seeing 4V or 11V suggests a problem. Edited January 18, 2023 by lotus10101
Checked Heaven and Cinebench, both performed well without issues and showed average results. The GPU worked smoothly with the default settings during Heaven, but it seems unstable in PUBG. I’ll attach the voltage readings I’m collecting. The first is for Heaven and the second for Cinebench. I’m having trouble locating a trustworthy download for membench—would linking one help?
This seems to be about memory training, though most RAM comes with a lifetime warranty. If issues persist after repairs, return the product via RMA. The PSU appears to be C tier hardware, which makes it easy to identify.
Your 12V and 5V rails seem really low, probably not ideal. I’d recommend upgrading the PSU.
An acceptable variation of 12v and 5v would be around .01 with fluctuations exceeding .5, and both 5v and 3.3v would behave similarly. This likely explains the slower speed you experience because of reduced demand.
