I've been experiencing a frustrating issue with my PC, where it sporadically crashes with a WHEA_UNDETECTABLE_ERROR BSOD. A local technician stress tested my machine under demanding conditions and didn't find any crashes for hours. They discovered some corrupt Windows files and fixed them, suggesting my HDD could be to blame. However, even with the HDD unplugged, the crashes continue intermittently. This has me puzzled because I can go weeks without an issue, and then I might see several crashes in a short time. I've also updated my BIOS and checked the health of all my drives, which appear fine, but I'm aware that those checks don't show the full picture. Generally, the crashes occur while gaming, though I've experienced them even when the system is idle.

Is your RTX 2060 a factory overclocked model? It's important because that can affect stability. Also, did they run Memtest86+ to check your RAM during the test? It could be a crucial factor if the RAM is faulty, which would be surprising considering it’s relatively new.
To really get to the bottom of this BSOD issue, we need to check the crash dump files. These logs can provide insights on what’s going wrong. If you can access Windows normally or through Safe Mode, look for the dump files in C:WindowsMinidump. If you find any, zip them up and upload to a file-sharing site like catbox.moe or mediafire.com. Having multiple files is helpful for analysis, so don’t worry if you find just one; we can work with that too. Also, consider adjusting your settings to create small memory dumps if you’re not getting enough data.

I’m not sure if my RTX is overclocked; it's an MSI NVIDIA standard model. I’ll need to check that. And, regarding the RAM tests, I don't think they did any specific tests since they weren't very communicative about their findings. I thought it was odd that they wanted payment before giving me a full report. I could reach out to them again to confirm what tests, if any, they ran.
