I have been experiencing a problem where my pc hangs up. It will hang up for no apparent reason. The only way that I have found recover is to power it off and back on. I had left it up while I went to dinner. When I returned the screen was blank and would not recover. Today I was on and I moved the mouse too fast and the screen popped with all of my desktops displayed. The mouse would move but I could not select any window. I am able to ssh into it from my laptop. Top and IOtop both respond in the ssh session. I even killed the user session with pkill but the pc was still unresponsive. I have check /var/log/messages for anything strange. I did not see anything apparently wrong. There are a bunch of messages like
AER: Corrected error received: id=0018
PCIe Bus Error: severity=Corrected, type=Data Link Layer, id=0018(Receiver ID)
device [8086:6f08] error status/mask=00000040/00002000
[ 6] Bad TLP
that happen arounf the time of the hang. I have searched for these errors and all that I have found have indicated that this is not a problem.
Here is a link to part of the messages file from before the hang till after the reboot.

I am running Fedora 26 64 bit with the KDE desktop. I will gladly supply any info that may help figure out what is happening.
Here is a link to the lshw output.
Thank you in advance.
