Hey guys,
I think I've posted this in the right thread.
I'm not sure if my problem is a hardware or a software issue.

When I'm using my system in a casual way without doing anything with a huge load my system keeps crashing briefly and then restoring.

So if I'm listening to music it starts to jump and the cursor will not move and another example is the smilies at the side of the message box stop moving as well as anything else running on the system. The whole system freezes and then continues as normal, it happens at irregular intervals and only crashes for a second or two and continues.

I've had a good look on Google and tried different things with my system and I've had no luck. Previously I have been using Windows 7 and I never encountered this problem but now I'm running Ubuntu 12.04 LTS 32bit as my only installation and now the problem has started.

Cheers.
