Hi all,

For a short while now every now and then my network connection drops out. Always when my computer is turned on for a while and further with no apparent reason. I did a complete reinstall recently from ubuntu 11.04 to ubuntu 12.04 hoping it would also solve this issue, but unfortunately it didn't.

My only solution so far is to restart my pc, sometimes it helps, sometimes I need to rest my computer for a minute before restarting. All seems to be indicating some kind of overheating problem. But that seems strange to me as it has always worked perfectly well. Maybe it just crashes in some other way?

Is there a way to be more sure about the problems? And if my network card would indeed be dying, any ideas on what my best options would be? Thanks.
