Periodic System Freezes

On a regular basis (approximately every half hour), my system locks itself up. During these freezes the hard drive spins wildly and both dual core processors run right at 100%. Gnome-System-Monitor does not register what is using the resources. These lock ups use so much of the system resources that I am unable to do anything until they stop. The mouse pointer barely moves and clicking anything doesn't enact until after the system calms down again. It usually takes about five minutes for the system to go through whatever it is doing and releases the hold it has on both the processors and the hard drive. However, sometimes it locks up so badly that I have to hard boot the machine in the middle of whatever it is doing. With the hard drive maxed out, this is obviously quite dangerous.

I simply CANNOT have this happening. To say getting locked out of my system could be catastrophic is a huge understatement. Last night my system was in screensaver (xscreensaver - blank screen) and the hard drive was running maxed out. I could not get into the system and had to hard boot at 10:35. This happens way to often.

The logs show very little unfortunately. I will post system information below along with the logs from last night before it was hard booted. I use XFCE as a desktop environment to minimize system load.

Please help. I need to have this system stable and operational at all times. Have been using Fedora since Core 1. Only the later versions have been doing this. I upgraded from FC25 hoping it would help, but it has not.
