   No HW issues, all other programs runs without problem except bitcoin. I made a backup of the wallet and deleted the folder .bitcoin 3 times to force a full resync, but same issue:

   The issue can be reproduced with a fresh installation from last release of bitcoin.

   Release used: bitcoin-0.16.0

   OS: Fedora release 27 (Twenty Seven) CPU: Intel(R) Core(TM) i7-3630QM CPU @ 2.40GHz RAM: 16317500 kB DISK TYPE: SATA Hitachi HTS54101 Rev: A4D0

   “all other programs runs without problem except bitcoin” is not sufficient to rule out hardware issues. Bitcoin is particularly good at breaking peoples’ hardware that is stable under low-load conditions. Please run memtest and linpack/prime95, and report the results.

   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

   Ok thanks I will check. In the meantime I’m installing bitcoin on another PC (unfortunately with windows).

   OK I confirm that on Windows PC everything is fine. Now I must investigate more why my laptop has this problem. memtest do not show errors, also disks seems ok. Only problem is a CPU overheat during the blockchain download. Thank you so much for your attention and sorry if I disturbed you for nothing.
