+ System froze unexpectedly. I had to press power button to reboot. All
+ started after I tried to use RecordMyDesktop for a video talk. I was not
+ aware how large the recording file would be. Then, I  ran out of space
+ in my HDD. After that I deleted the files RecordMyDesktop had saved and
+ a bunch of other multimedia files to release free space. Since then my
+ system freezes randomly. My WIFI connection became very unstable also.
+ 
+ To work this out, I upgraded my kernel to HWE (raring) and flashed a
+ more recent Bios.
