Long story short I am not a newbie with this situation I had the problem a few years back on openelec but ended up with installing kodibuntu and not had one problem with this freezing issue since.
These ares some operating systems I have tried with this system and you can see the outcome.
openelec - 4.2.1 = froze 3 times in 1 hour
openelec - 4.97.2 = froze once in 2 hours
enelec - 6 = same problem as above
windows 10 = froze after 4 hours, but was also too buggy (tried this again at the end of 2016 and still froze)
windows 8.1 = froze after 76mins
Linux mint 17.1 = lasted the longest 3hrs 8mins before it froze.
My system which I only use for Kodi
AMD Athlon 5350
Kingston HyperX Fury Blue 4GB (1x4GB)
Asus AM1I-A
120GB OCZ SSD
Strider SST-ST30SF SFX Series
Though yesterday I did a core update with kodibuntu and it messed everything up it actually took kodi back to 15.2 Isengard and deleted all my addons.
So I thought I would go back to openelec but seeing as that's still on 16.1 I thought I would give LibreElec a chance.
I installed it got all my addons back started watching a film and guess what the system froze once again this had not happened in quite some time and is very annoying.
Personally I think the onboard graphics is the problem because when I have installed a dedicated GPU it's never froze once so really I should purchase a card for this machine which is long overdue.
Anyone else ever had this problem? and why is it still ongoing.
Thanks for any help and advise.
