HELP! System keeps locking up

[bc98kinney]

Lockups can come from bad memory, so I would recommend you run memtest86 before anything else. Sometimes you have to let it go for a couple days before it finds anything.  A non destructive drive test like DFT wouldn't be a bad idea either.

Subject: HELP! System keeps locking up 

Hello, all...
I'm running Fedora 20 on a homebrew PC It's an AMD Athlon X2 processor with an 
on-board nVidia display chipset. 
This is a fresh install of F20, pretty much up to date. I had to do a fresh 
install since I mangled the upgrade from F18.
Every once in awhile, mainly when I'm trying to unlock the screen, the system 
will freeze up. My display is a black background with "bits" of color in a 
diagonal pattern. 
I say "mainly when trying to unlock the screen" because I had it happen to me 
this morning (third time in 24 hours) when I was thinking of trying a different 
screen saver (been using Moebius Gears) on the thought that maybe the Noveau 
driver doesn't like the GL screen saver for some reason.
Every time this happens I have to use the reset button on my system. This 
morning when it happened, I had an SSH window from another PC logged in and it 
was frozen as well.
I have checked /var/log/messages and there is nothing in there that would 
indicate a problem. There was hardly anything in there since about 8PM last 
night and it's locked up twice since then.
Suggestions/thoughts/theories??? 
I'm running XFCE, if it matters, but still using parts of KDE as well.
