Anybody else want to put their foot through their computer?
Regularly, usually because I end up on hardware support, worming my around server rooms trying to extricate a blown power supply or whatever.
More personally I recently (~3 months ago) bought myself an ATI 4890 card and, alas, one of the memory chips was faulty. The reseller wasn't interested in trying to solve the problem in a reasonsable time frame so I took it back to the importer. Unfortunately the problem was way beyond the poor techie I got assigned - she had her diagnostics software (which wasn't failing) and didn't really know what to do. After some back and forthing I got the card swapped out. Which should have been the end of it.
Only whilst trying to get the faulty card to work I (unknowingly) completely buggered up the drivers. So now the new card starts failing erratically - which is about where I *really* wanted to put my foot through my computer. However said card wasn't behaving like it was a hardware problem but no amount of uninstalling and reinstalling of drivers would make it work. Finally - in desperation - I wiped windows and reinstalled which fixed it.
The whole episode was time consuming and unpleasant but - that said - I'd still heartily recommend the 4890. It really is an excellent piece of hardware and no games have taxed it yet (including Fallout 3 with mega-texture packs, greenworld and enhanced models).
[EDIT] Don't I feel like a prat now. I meant 4890, not 4870
