I recently installed linux mint 19 xfce on my laptop and keeps happening very often (randomly between 15min to a few hours) that it completely freezes and it doesnt respond to any commands, after a couple of seconds the fan speeds up just stays like that and im forced to hard reboot it.
I've tried to google for solutions and what i found is mostly for nvidia graphics but mine is not, also found a reference mentioning the realtek card but im not sure how it is related. I havent noticed anything special that triggers it, it seems to happen randomly, sometimes when the browser is open, sometimes a video, sometimes nothing at all. I also tried checking the syslogs whenever it happens but there seems to be nothing being written at the times it happens.
a post in the forum recommended trying an older kernel but it didnt help in this case, also i dont think its a hardware problem because it doesnt happen if i boot to windows 10
Anyone had a similar problem or can point me to something else i could check? this is my system
