PPT/TDC/EDC are power limits that along with thermal limit restricts the frequency that Precision Boost will allow the processor to reach. The reason you're seeing the power limits in the red is because the R5 5600 is a 65W TDP chip, so the limits have been set purposefully low (76W/60A/90A) to keep TDP and temperature down.
As to the crashing, what CPU cooler are you using and what temperature is the CPU reaching when these crashes occur?
