[Lxde-list] Problems in lxqt but it seems that i have hardware problems

[Dimitrios G. <dg...@fr...>]

Hi, i cannot work in lxqt, i have many problems, sometimes i after loggin 
and when it starts the session it jumps back in dm manager
If i can have the session, the menu doesn't open, i cannot do right click, 
applications open but the system is not usable.
I tried kde5 the same problems
With kde4 it is quite usable but time to time i have crashes especialy with 
qt5 applications (as i see in logs)

kernel: [  216.856191] lxqt-session[5777]: segfault at 0 ip 
00007f80985df533 sp 00007fff85aa9cc8 error 4 in 
libQt5Core.so.5.4.0[7f80984d9000+4af000]

I have two memory sticks and i have tried with both (one by one), same 
behavour.

I'd like to ask if someone could with a look in 
http://glenbox.free.fr/files/Mageia/syslog_lxqt_errors
(search keywords: "error", "trap", "segfault")
http://glenbox.free.fr/files/Mageia/lspci
tell me his opinion

I have the feeling that is a motherboard (asus M4A77TD PRO) problem.
Thanks in advance and sorry for the, normaly, non software issue
