   Bitcoin Core makes heavy use of CPU, RAM and disk IO. Hardware defects might only become visible when running Bitcoin Core. You might want to check your hardware for defects.

   • memtest86 to check your RAM
   • to check the CPU behaviour under load, use linpack or Prime95
   • to test your storage device use smartctl or CrystalDiskInfo
