I would suggest that computer frustration differs from normal frustration in important ways.

Regular frustration is the experience of feeling limited or thwarted in your efforts towards any particular end. It normallly has a number of physical (slow, cold sweat, tightening of the chest, shortness of breath) and psychological (racing thoughts, violent fantasies towards the thwarting party) symptoms.

Computer frustration, however, differs from the frustrations encountered in just about any other domain or endeavour. When a computer becomes the thwarting party, for whatever capricious reason, the psychological symptoms become acute while the physical symptoms disappear, only to be replaced by an intense desire to drink copious amounts of tequila.

Or maybe spending 6 hours reinstalling an OS is just taking its toll on my psyche.

Well, I'm off to find a replacement for Francine.
