Have you tested the RAM using Memtest86 from Grub?

Couldn't use the web to find out for yourself......?

If you reboot and hold SHIFT, you will see Grub. Use cursors to select Memtest86+

This is good:

This is bad:

Tested ram using grub and the results are healthy. Perhaps I should re-install the operating system?

Install the xfce4 package and log off. Login to the new XFCE session and test. Is it OK?

Can you help with this problem?
