You got some uninformed noise in response to your HDD information. See
for how to read such reports. In fact there's no indication of trouble in 
your report (though a firmware update may be a good thing).

Here are the lines that someone said were problematic:

    1 Raw_Read_Error_Rate     0x000f   118   099   006
    7 Seek_Error_Rate         0x000f   077   060   030

The thing is the _small_ values are bad here (a value less than THRESH is 
considered a failure). Your values are perfectly healthy.

This seems more relevant: you have about 90% of RAM in use and are well 
into swap. With your system in that position I can see that it might take 
a while to start up another big application. Maybe you're running 
something that's gradually leaking memory.
