I have a problem with unpredictable unresponsiveness of the system while I'm working. I can't isolate a specific cause, as it appears to be completely random, but I'll be working along, open a window or do something like click on a button in a comma-delimited file, or be working in an email, and the next thing I know is that I can't type.
The keyboard is unresponsive. Shift lock and Number lock do not work. The left and right mouse buttons don't work. The mouse cursor moves, but that's the only thing that does. Alt+SysReq+R+E+I+S+U+B does nothing. Ctrl+Shift+F1-F6 does nothing. It's like the USB system is glitching, but it's permanent and NOTHING I do can unstick it or get it to start working again.
I've attempted to connect another USB keyboard (the normal one is a wireless Logitech keyboard and mouse that normally work well) but the second keyboard does nothing. It's like the USB system is shut down.
The ONLY way I can stop this is to hold down the power button and I lose everything. This really is not optimum. But I've seen many posts where heynnema walked through these problems and was able to pinpoint what was wrong, but I've not seen any where the tty console couldn't be conjured up and something done. This is a complete loss of the keyboard and any functionality of the machine.
Any ideas on where to start? Intel Core i7-3770CPU @ 3.4Ghz, 4 cores, 16 GB ram, Nvidia GeForce GTX 550Ti, 1 GB ram; American Megatrends 2014 Bios, Asustek Computer Motherboard P8-Z77-V.

That's all that's there. I think that's a problem, but I have no idea of how to fix it. Will check on the memory slots now.
I verified there are 4 physical memory slots in the motherboard. They are each filled with a 4 GB memory module.
I have pasted the results of cat /var/log/syslog on Ubuntu Pastebin

FWIW, the Patriot Memory modules were in this CPU when I purchased it. If they are the problem, then this is probably why the original owner sold it to me at a very steep discount, and he probably had problems with it.
After following heynnema's directions to remove /etc/openVPN/HMA.conf:
$ sudo rm /etc/openvpn/HMA.conf
$ cat /etc/openvpn/HMA.conf
cat: /etc/openvpn/HMA.conf: No such file or directory
It is now removed.
