You might also check your CPU temperatures. Also, if you have a can of air, blow it into your vents to clear any dust off of the CPU cooling fins and fans.

The RAM does seem to get high and goes into swap sometimes. I have actually been looking at the System Activity window during a crash and didn't see a CPU issue. I have 4gigs of ram and can't add more to this machine. It is generally Chrome and Firefox that use up the most, and I generally use them at the same time for different tasks. I don't know what baloo or akonadie are. how do I check on them?

It happened again, and this time it was definitely in stages. things started to get flaky, like when I opened the save dialogue in GIMP with my Wacom tablet pen, none of fields would work. I had to close and re-open it with the mouse. This went on for 5 minutes, then the cursor froze, then the keyboard became unresponsive, then the music that Amarok was playing stopped. It certainly seems like system thing and not just input devices. I have been lucky so far and have been able to have work saved and not lost a critical piece in a crash. it is just a mater of time though. Can someone please give me some place to look for help?

You are correct, it was not happening on the previous version. I believe the version I was using before was 12.04. The HDD is new. I had to completely re-install because I had not created a large enough root partition to upgrade to. Now there is plenty of room in the root partition.

Am I correct in assuming that prior to the fresh install of 14.04 these issues were not happening? If that's correct, what version was running on this computer before the fresh install? And was this new hard drive not previously used in this computer?

Input freezing and/or crashing
I recently fresh installed kubuntu 14.04 on my pavilion AMD64 with new 1TB HDD. I am using the stock PS2 keyboard and a logitec wireless USB mouse.
At random times the input devices become unresponsive requiring me to REISUB. It happens sometimes after several hours of work and sometimes after just 30 minutes. Sometimes the input freezes and after a couple seconds the screen goes black and it goes to the login screen as if it just rebooted. Sometimes it just stays frozen. Sometimes (rarely)it just goes directly to the login screen without freezing. Sometimes the keyboard remains active long enough for me to test if it is working like hitting the caps lock and seeing the light come on.
It seems to do it when I am using the mouse, but not always, I have found it gone to the login screen when I have left it unattended for a while.
This has been going on for a few weeks now and I have not found any solutions from online searches.
I honestly don't know if it is an input driver crash, a KDE crash, or something else. The last couple times it happened, the freeze happened in short stages. first clicking became unresponsive, then the cursor froze, then after a few tries where it worked, the Num Lock stopped responding.\
I have run memory tests and there are no errors. I have tried using a PS2 mouse and had it freeze up.
If there is anyone out there that can point me in the right direction or help me troubleshoot, I would be grateful. It is really becoming a problem.
