2012 mac pro shuts down instead of sleeping

I have a 6-core mid 2012 Mac Pro that has had problems going to sleep. When the computer tries to sleep-either manually or automatically, it will panic shut down. I've had it to an independent but authorized repair center and they simply removed one of my two video cards and stated that there was too much of a poor draw on the power supply and this is what was causing the problems. Indeed, this did fix the problem for about 3 months, but now its back. This is what I found when I ran the command pmset -g assertions :

I'm running the latest version of El Cap, and as a noob to command line, I was wondering if anyone sees anything out of the ordinary, especially the line "com.apple.iohideventsystem.queue.tickle"

My next step would be to obviously take the unit back in, but if they're on a bad power supply kick, I'm going to be out a $350 and my hunch is that a new power supply is not the problem.

Thanks in advance!

Mac Pro, OS X El Capitan (10.11.3), Mid 2012 3.33 GHz 6-Core Xeon

Thanks so much for the quick reply!

Okay. I hope this is what you're looking for. Given that its a Wacom tablet driver, I'm inclined to delete it. But, as you can see, there are more issues going on here than just the Wacom driver. The machine will kernel panic each and every time I try to sleep it.

Yes, try deleting the Wacom drivers.

You can easily post a crash by going to Consol and select the crash in right like you did and then go to Edit and select Select All and the copy and then past in a reply here.

Got it. I'll delete the Wacom drivers and then sleep the computer and see what happens.

Of course it couldn't be that easy. There are no drivers installed but fragments of the application. I've trashed them but I still have the icon showing up and nothing that is "clickable" in the drop down menu. Arrrg!

Third one from the left. I'me beginning to wonder if re-installing the OS wouldn't help?

Sorry to bombard you with so much info. I found the Wacom drivers following the path in the crash report. I trashed them and the icon no longer shows up. I restarted the machine and tried to make it sleep. Same result- a panic shut down. I pulled the report but it did not log an additional crash/shutdown. Again, ASAIK, Wacom has been trashed(not uninstalled).

Here's a clip from the report. I can't publish the whole report because by copy and pasting I apparently introduce invalid characters that the forum won't let me use.

Is the Wacom still connected?

If so disconnect.

Does Walcom have new drivers?

Wacom is disconnected. I tried to re-install the OS but failed. About half way through the process, I received a message that one of the Volumes was damaged and the installation could not continue. This is with a verified good copy of OS X 10.11.2 via thumb drive. So now I'm back to where I started from. Kind of. After all that, I was able to get the computer to sleep once. It took about 30 seconds from the sleep command to the computer sleeping (glowing power light). That seems like quite a long time. It now won't sleep and I'm back to a panic shut down, although there are no new logs to show this- which I find strange.

I think my next step will be to back up and do a clean install.

This "I received a message that one of the Volumes was damaged and the installation could not continue" indicates a possible failing disk.

I Agree. However, the OS is located on an SSD and I can't believe that could be faiiling, although I suppose anything is possible. I removed the thumb drive that contained a bootable copy of OS X out and after a few attempts the machine booted correctly. I'm not at the machine now and won't be home for two days now.
