My custom-built gaming PC has started experiencing random, intermittent blue screen crashes, usually when under load, but sometimes even at idle, and the error codes are different each time, which makes PC troubleshooting incredibly frustrating. I've run memory diagnostics and checked my drive health, and everything comes back clean, so I'm suspecting it could be a failing power supply or a motherboard issue, but I don't have spare parts to swap for testing. For experienced builders, what would be your systematic approach to isolate the faulty component when dealing with inconsistent crashes? I'm particularly interested in software tools for stress-testing individual components or any BIOS settings I should double-check that might point to the culprit.
