My work computer suddenly started freezing

I work from home, so this is causing me a bit of anxiety. I'm not a total Linux noobie, but I don't know much about diagnosing problems, so bear with me, please.

I always do my job from Workspace 1, and I have YouTube and any personal stuff on Workspace 2. For work, I use the Citrix Workspace environment via Opera. Today my Citrix environment froze, and I got a message saying it was trying to reconnect to the internet (which it never did). Meanwhile my YouTube video, my internet, and all my browser windows on Workspace 2 were still working fine, so I figured it was a problem with my company's servers.  I rebooted the computer, brought everything back up, and after a while, it happened again. I decided to stop working and do some browsing on Workspace 2. Not long after, that froze solid as well. I rebooted and I'm trying to figure out what is going on.
After rebooting this time, I ran the System Monitor - nothing shocking there, as far as I can tell. Then I ran an animation on Blender, which used more resources, but didn't max them or cause a freeze-up.
Previously I have occasionally had my Citrix environment freeze or get really sluggish when I was playing YouTube in Opera's media pop-out window, and when I turned that off, it would work again.
Any help is, of course, greatly appreciated.
