Many useful ideas were shared, so thanks for the recommendations. I was told by others that RAM problems might be the issue, which is new to me regarding brand compatibility. I’m planning to install a memtest program on a USB drive and run the test soon; I’ll have more time in the next few days. I’m trying to learn about UEFI, a term I don’t understand well. My motherboard already has the newest firmware, though. I didn’t adjust any RAM speed settings—I thought the board would auto-detect it. While I see the POST handled everything, I’m still checking other settings. I’m considering switching to PCIe 4.0 if it affects performance, but I’d rather fix an incompatible part than limit the functionality of the new gear I just purchased. Thanks again for your help—I’ll share my findings later. You all did a great job!
The issue seems to improve when running at standard speeds, though I'm not sure. Memory testing is useful but won't catch everything—only identifies clearly faulty RAM. With a 5xx chip, it might just be driver-related. PCIe4 could also help, causing minimal performance impact (~1%).
Update from memory check: Memtest 86 detected no issues in two out of four runs. I left the rest to finish overnight. Upon waking, the system didn’t respond—possibly due to a failed or incomplete test. I’m checking for a log file later when I have time. I noticed the BIOS had memory acceleration enabled and mem speed set to auto-detect. I switched it off and adjusted the speed using XMP settings, which were already in place before the test. Since those were set earlier, they might have helped. If restarts persist, I’ll proceed with PCIE4 and updating the BIOS with the latest version. I’m cautious about newer Nvidia drivers, so I’ll hold off on that until then.
Ultimately decided to purchase a new motherboard after fixing the RAM and SSD, yet the issue persisted repeatedly. It seems challenging to eliminate, making it the final component to address.
