My custom-built rig ran fine for 7-8 months. A couple of months ago, it started spontaneously rebooting after about 30 minutes or more using Lightroom. After updating Windows, video drivers, and BIOS, it now reboots within 2-3 minutes of launching Lightroom. This appears to be related to high CPU temps. I applied new thermal paste to the CPU/heat sink and added an additional case fan, but the issue still occurs. CPU and case fans all appear to be running at appropriate speeds.

- Intel Processor Diagnostic tool says the CPU passes all tests.
- Ran a prime95 stress test and the machine rebooted about 3 minutes into the test. Clearly a fail.
- AIDA64 shows the CPU running overclocked at 15-18%. This appears to be automatic from AI Tweaker, could this be the issue? Can it be disabled?
- Other ideas on potential causes?
